Definitions
- the present invention relates to a method for producing an anhydride of a 2-(. 2-aminothiazole-14-yl) -12-hydroxy compound. More specifically, the present invention relates to a novel hydrate of a 2_ (2-aminothiazole-41-yl) -12-hydroxy compound represented by the following general formula and a high yield of an anhydride. Related to manufacturing method.
- R 1 represents an acyl group, a protected carboxy (lower) alkyl group or an alkyl group.
- Aminothiazole derivatives usually have one or two molecules of water of crystallization.
- An object of the present invention is to efficiently remove obstacle water of crystallization in order to synthesize an acid chloride of an aminothiazole derivative.
- an object of the present invention is to provide a novel industrial method for producing an anhydride of 2- (2-aminonotiazo-1-yl) -12-hydroxy compound.
- the inventors of the present invention have conducted intensive studies on the industrial production of 2- (2-aminothiazole-4-yl) 1-2-hydroxy compounds, and as a result, have found that 2- (2-aminothiazole-1 4 Ill) _ 2 — We have succeeded in completing a new production method that can easily remove water of crystallization from crystals containing water of crystallization of hydroxy compounds.
- the anhydride of the 2- (2-aminothiazolyl-41-yl) _2-hydroxy compound (I) obtained by the production method of the present invention is reacted with a haematogenic agent such as phosphorus pentachloride. Reacts with 7-aminocephalocompound as acid chloride hydrochloride (A) to inhibit the growth of a wide range of pathogenic bacteria, including Gram-positive and Gram-negative bacteria, and to provide antimicrobial agents.
- a haematogenic agent such as phosphorus pentachloride.
- Suitable "acyl groups” include aliphatic acyl groups and acryl groups containing an aromatic or heterocyclic ring. Preferable examples of these acryl groups include, for example, formyl, acetyl, propionyl Lower alkanoyl groups such as, butyrinole, isoptyl, parryl, isonorelyl, oxalyl, succinyl, pivaloyl;
- Lower alkoxycarbonyl groups such as, for example, methoxycarbonyl, 1-cyclopropylethoxycarbonyl, isopropoxycarbonyl, butoxycarbonyl, tert-butoxycanoleponyl, pentinoleoxycanoleponyl, hexinoleoxycarbinole;
- Lower alkans norehoninole groups such as, for example, mesinole, ethanes / lefonyl, prononsulfonyl, 1-methylethanesnolephonyl, butanesulfonyl;
- arenesulfonyl groups such as benzenesnolephonyl and tosyl, etc .
- alkenyl (carbonyl) groups such as phenylacetyl and phenylpropionyl are exemplified.
- acyl moiety may have at least one suitable substituent such as chlorine, bromine, halogen of fluorine and iodine.
- suitable “protected carboxy (lower) alkyl groups” include, for example, esterified carbonyl (lower) alkyl, and more preferably lower methoxycarbonylmethyl, tertiary butoxycarbonylethyl and the like.
- Mono- or di- or triphenyl (lower) alkoxycarbonyl (lower) alkyl such as alkoxycarbonyl (lower) alkyl, benzhydryloxycarbonylmethyl, alkyl, chloromethoxycarbonyl methinole, 2-hydroxyethoxycarbonyl Mono- or di- or tri-cyclo (lower) alkoxycarbonyl (lower) alkyl such as methyl.
- Suitable “alkyl groups” include methyl, ethyl and the like. It is.
- Powder X-ray diffraction (peak angle: 20): 2 : -14.7 °, 16.0 °, 19.0 °, 19.5 °, 20.5 °, 21.4 °, 24.5 °, 25.5 °, 25.8 °, 21.2. Near 30.2 °, 8.9 °, 14.3 °, 15.3 °, 17.2 °, 18.4 °, 19.6 °, 21.0 °, 22.3 °, 24.3 °, 26.7 ° It has an X-ray diffraction image with no diffraction peaks at around 27.5 °, 28.5 °, and 29.0 °.
