Since compound (2) used in the first step gradually decomposes in the presence of water, there has been a concern that the resulting decomposition products themselves can be impurities, and may react with the target product or other impurities to generate new impurities in the production of rivaroxaban as pharmaceutical. [0011] Moreover, the solvent to be used in the second step of obtaining compound (3) is different from that to be used in the step of obtaining compound (4) from compound (3), so that compound (3) must be isolated also in the second step.

[4] A method for producing a compound of formula (6), comprising the method as defined in [2] or [3] for producing hydrochloride of compound (4), and step 5: reacting hydrochloride of compound (4) with a compound of formula (5): (hereinafter referred to as compound (5)) in the presence of a base to obtain compound (6). [0014] [5] The production method according to any one of [1] to [4], wherein trifluoromethanesulfonate is zinc(II) trifluoromethanesulfonate, ytterbium(III) trifluoromethanesulfonate or aluminum(III) trifluoromethanesulfonate. Mode for Carrying Out the Invention [0015] The present invention will be described in detail below. Step Step 1 will be described. In step 1, compound (1) is reacted with compound (2) in acetonitrile in the presence of trifluoromethanesulfonate. [0016] Examples of trifluoromethanesulfonate include trifluoromethanesulfonic acid metal salts such as zinc(II) S426 trifluoromethanesulfonate, ytterbium(III) trifluoromethanesulfonate, aluminum(III) trifluoromethanesulfonate, lithium trifluoromethanesulfonate, calcium trifluoromethanesulfonate, iron(II) trifluoromethanesulfonate, copper(II) trifluoromethanesulfonate and bismuth(III) trifluoromethanesulfonate, and triethylsilyl trifluoromethanesulfonate, of which zinc(II) trifluoromethanesulfonate, ytterbium(III) trifluoromethanesulfonate and aluminum(III) trifluoromethanesulfonate are preferable, and zinc(II) trifluoromethanesulfonate and ytterbium(III) trifluoromethanesulfonate are more preferable. Trifluoromethanesulfonate may be an anhydride or a hydrate, and commercially available products can be directly used. [0017] Trifluoromethanesulfonate is usually used in an amount of 0.01 mol to 0.20 mol, and preferably 0.02 mol to 0.07 mol, per mol of compound (1). [0018] The compound (2) is usually used in an amount of 1 mol to 1.5 mols, and preferably 1.00 mol to 1.05 mols, per mol of compound (1). [0019] Acetonitrile to be used in step 1 more preferably has lower water content. If acetonitrile has higher water content, compound (2) may be decomposed by water, and 1,1′-carbonyldiimidazole to be used in step 2 is hydrolyzed, which is not preferable. Therefore, the water content of acetonitrile to be used in step 1 is usually 0% to 0.05%, 30 S426 preferably 0% to 0.02%, and more preferably 0% to 0.01%. The water content of acetonitrile can be measured by the Karl Fischer method. [0020] Acetonitrile may be used in an amount of 3 parts by weight or more, usually 5 parts by weight to 20 parts by weight, and preferably 7 parts by weight to 15 parts by weight, per part by weight of the compound (1). [0021] The reaction is performed by mixing compound (1), compound (2), trifluoromethanesulfonate and acetonitrile. There is no particular limitation on the mixing order of compound (1), compound (2), trifluoromethanesulfonate and acetonitrile. For example, it is possible to perform the reaction by a method in which acetonitrile, compound (1) and compound (2) are mixed, and then trifluoromethanesulfonate is added; and a method in which compound (1), compound (2) and trifluoromethanesulfonate are mixed, and then acetonitrile is added. [0022] The reaction temperature is usually in a range of 1°C to 80°C, and preferably 5°C to 55°C. [0023] The reaction time is usually 1 hour to 60 hours. [0024] By this reaction, a mixture containing compound (7) can be obtained. [0025] The mixture obtained in step 1 can be directly fed to step 2. 30 S426 Step Step 2 will be described. In step 2, the mixture obtained in step 1 is reacted with 1,1′-carbonyldiimidazole to obtain compound (3). [0026] 1,1’-carbonyldiimidazole is usually used in an amount of 1 mol to 3 mols, and preferably 1.0 mol to 1.5 mols, per mol of compound (1) used in step 1. [0027] The reaction is performed by mixing the mixture obtained in step 1 with 1,1’-carbonyldiimidazole. From the viewpoint of the operability, it is preferable to add 1,1’-carbonyldiimidazole to the mixture obtained in step 1. To add 1,1’-carbonyldiimidazole to the mixture obtained in step 1, the whole amount of 1,1’-carbonyldiimidazole may be added at once, or 1,1’-carbonyldiimidazole may be added in plural portions. [0028] The addition is usually performed in a range of 1°C to 80°C, and preferably 5°C to 55°C. [0029] The reaction temperature is usually in a range of 1°C to 80°C, and preferably 40°C to 80°C. [0030] The reaction time is usually 1 minute to 10 hours. [0031] After completion of the reaction in step 2, for example, compound (3) can be precipitated and isolated by mixing the reaction mixture with an insufficient solvent. [0032] 30 S426 Examples of the insufficient solvent include hydrocarbon solvents such as heptane, toluene and xylene; halogenated hydrocarbon solvents such as monochlorobenzene; ether solvents such as diisopropyl ether and methyl tert-butyl ether; alcohol solvents such as methanol, ethanol and isopropyl alcohol; and water, of which toluene, methanol or ethanol is preferably used. [0033] The insufficient solvent is usually used in an amount of 2 parts by weight to 20 parts by weight, and preferably 5 parts by weight to 15 parts by weight, per part by weight of compound (1) used in step 1. [0034] The mixing is usually performed in a range of 1°C to 60°C, and preferably 20°C to 60°C. From the viewpoint of the operability, the mixing is preferably performed by adding the insufficient solvent to the reaction mixture. [0035] By the mixing, compound (3) is usually precipitated as crystals. To accelerate the precipitation of compound (3), seed crystals of compound (3) may be added, if necessary. [0036] When the seed crystals are added, the amount thereof is 0.001 part by weight to 0.01 part by weight per part by weight of compound (1) used in step 1. The addition is usually performed in a range of 1°C to 70°C, and preferably 20°C to 60°C. [0037] Crystals are precipitated by mixing the reaction mixture with the insufficient solvent and, if necessary, seed 30 S426 crystals, followed by holding usually at -20°C to 60°C, preferably -5°C to 20°C, usually for 1 minute to 24 hours, preferably 1 hour to 15 hours. [0038] The precipitates of compound (3) can be obtained in accordance with the solid-liquid separation method. Specific examples thereof include solid-liquid separation operations such as filtration and decantation. Compound (3) obtained by the solid-liquid separation operation may be washed with a solvent, if necessary. Examples of the solvent to be used for washing include hydrocarbon solvents such as heptane, toluene and xylene; and alcohol solvents such as methanol, ethanol and isopropyl alcohol; of which toluene, methanol or ethanol is preferably used. [0039] Compound (3) can be dried under normal pressure or reduced pressure. [0040] Compound (3) thus obtained usually has a purity of 99% or more. The purity can be confirmed by analytical means such as gas chromatography (GC) and high performance liquid chromatography (HPLC). [0041] Compound (3) thus obtained may be further slurry washed by mixing with the insufficient solvent under stirring. [0042] After completion of the reaction in step 2, compound (3) can also be fed to step 3 without purification. That is, the mixture obtained in step 2 can be directly fed to step 3. 30 S426 Step 2’ Step 2’ will be described. In step 2’, the mixture obtained in step 1 is reacted with 1,1’-carbonyldiimidazole. The reaction can be performed in the same manner as in step 2. The mixture obtained after completion of the reaction in step 2 can be fed to step 3’ without purification. That is, the mixture obtained in step 2’ can be directly fed to step 3’. [0043] The mixture obtained in step 2’ includes the compound (3). Step Step 3 will be described.

[0045] Compound (3) may be obtained as a mixture in the reaction of step 2. When the mixture obtained in step 2 is S426 fed to step 3 as it is, the solvent used in step 2 can be used as it is, or the solvent may be further added thereto. [0046] Methylamine is usually used as a liquid composition after mixing with a solvent. Examples of the solvent include methanol, ethanol, isopropyl alcohol and water, of which methanol or water is preferably used. Commercially available liquid compositions such as an aqueous methylamine solution may be used as it is. [0047] Methylamine is usually used in an amount of 1 mol to mols, and preferably 3 mols to 7 mols, per mol of compound (3). [0048] The reaction is performed by mixing compound (3) with methylamine. In the mixing, the order of mixing is not particularly limited, and examples thereof include a method in which methylamine is added to a mixture of compound (3) and a solvent; and a method in which compound (3) is added to a mixture of methylamine and a solvent. [0049] The reaction temperature is usually in a range of 10°C to 80°C. [0050] The reaction time is usually in a range of 1 minute to 6 hours. [0051] After completion of the reaction, compound (4) can be directly fed to step 4 without purification. That is, the mixture obtained in step 3 can be directly fed to step 4. 30 S426 id="p-52" id="p-52" id="p-52" id="p-52" id="p-52"

[0055] Compound (4) may be obtained as a mixture in step 3 or step 3’. When the mixture obtained in step 3 or step 3’ is directly fed to step 4, the solvent used in step 3 can be used as it is, or the solvent may be further added thereto. [0056] As hydrogen chloride, hydrochloric acid (an aqueous solution of hydrogen chloride) or a hydrogen chloride gas is usually used. [0057] When using hydrochloric acid, the concentration thereof is not particularly limited, and hydrochloric acid having the concentration of 5% by weight to 35% by weight is preferably used.

[0060] The reaction temperature is usually in a range of 10°C to 70°C. [0061] The reaction time is usually in a range of 1 minute to hours. [0062] After completion of the reaction, a hydrochloride of compound (4) is precipitated, for example, by concentrating the reaction mixture; or by holding the reaction mixture at -20°C to 70°C, preferably -5°C to 60°C, for 1 minute to 20 hours.
