A good yield can be obtained when the pH adjusted in the present invention is 3.0 to 5.0, and in particular, the highest yield and practical reaction rate can be obtained when the pH is 3.5 to 4.5. If the pH is less than 3.0, the yield decreases due to side reactions as the acidity increases. Moreover, if the pH exceeds 5.0, a practical reaction rate cannot be obtained due to a decrease in the reaction rate, and no reaction occurs at all under neutral conditions. Since the adjusted pH increases as the reaction progresses, acid is continuously added to cause the reaction to occur.

The acid used in the present invention can be an acid that has the strength to maintain the pH used in the present invention, mineral acids such as hydrochloric acid, sulfuric acid, and cynic acid, and organic acids such as formic acid and l-toluenesulfonic acid. Preferred are hydrochloric acid and sulfuric acid, which are inexpensive and used industrially, and can provide high yields. These acids may be diluted with water, but there is no particular need to do so, and those with high concentrations that are generally used industrially can be used as they are. The amount of acid varies depending on the strength of the acid used, but is usually 1.2 to 5.0 equivalents relative to compound (1). Formamide methylolation compositions containing compound (2) are generally known. For example, formamide is dimethylolated with formaldehyde using a basic catalyst such as sodium hydroxide or potassium carbonate. This methylolated composition is composed of compound (1), formamide, N,N represented by the formula (HOCH2)2NCHO
-bis-(hydroxymethyl)formamide, and the composition ratio differs depending on the molar ratio of formamide and formaldehyde used, and the molar ratio of formamide and formaldehyde is at least formamide/formaldehyde.
When formaldehyde is 21 or more, preferably 1.2 or more, the content of compound (1) is large and good results are obtained in this reaction. If formamide is used in large excess, the yield of compound (1) will be maximized, but economically, the ratio is preferably 3 or less. A high yield can be obtained when the amount used is 2.0 equivalents or more of formaldehyde per tolylsulfinate. Formaldehyde can be used as a monomer, but for ease of handling, formalin (37% content), which is an aqueous solution of formaldehyde, or Nora, which is a commercially available linear low polymer of formaldehyde, is usually used. Formaldehyde (70-90% content) can be preferably used. When formalin is used, better results can be obtained if the water is distilled off after methylolization, but when using formaldehyde, it can be used as is for the reaction without distilling off the water. This is especially convenient.

Compound (2) can be a monovalent metal salt such as sodium or potassium, or a divalent metal salt such as calcium, and can be prepared by a generally known method, for example (Ber, Dtsch).

The reaction temperature is usually 60 to 100°C, but a temperature of 75 to 95°C is preferably used because when the temperature is low, the reaction is slow, and when it is high, a decomposition reaction is caused and the yield is reduced.

When the above-mentioned conditions are appropriately combined, Compound I can be easily obtained in high yield, and there is usually no need for purification. Therefore, when extracted with a solvent after completion of the reaction, the solution containing Compound I can be used as it is in the next reaction, for example, the synthesis of tosylmethyl isocyanide, by simple operations such as washing with water. If particularly necessary, the desired purpose can be easily achieved by recrystallizing from a solvent such as alcohol.

If formamide is used in large excess, the yield of Compound I will be maximized, but economically, the ratio is preferably 3 or less. The amount used is p-) A high yield can be obtained when 2.0 equivalents or more of formaldehyde is used relative to IJ rusulfinate. Formaldehyde can be used as a monomer, but for ease of handling, formalin, which is an aqueous solution of formaldehyde (with a content of about 37%
h) or commercially available formaldehyde linear low polymer Zuraformaldehyde (content about 70 to 90 h)
can be suitably used. When formalin is used, better results are obtained if the water is distilled off after methylolization, but when formaldehyde is used, it can be used as is for the reaction without distilling off the water. This is especially convenient.
