的方法においての調整は至難である。 For example, glyoxal is oxidized with nitric acid to produce glyoxylic acid, and an acid with stronger acidity than this acid is used as a catalyst to produce the compound of the formula at a temperature of 65 to 95%.
A method in which glyoxal is reacted with urea at a temperature of 50 to 100 degrees Celsius (see Japanese Patent Publication No. 46-2095).
A method is known in which the material is heated for 120 minutes and then reacted with urea (see Japanese Patent Publication No. 11918/1983). However, with these methods, it is almost impossible to industrially purify glyoxylic acid obtained by oxidizing glyoxal, and it has to be used as a raw material containing oxidized by-products and unreacted substances. It is extremely difficult to obtain the intended purpose as a pure product. Furthermore, the range of reaction conditions is very narrow, making adjustment in industrial methods extremely difficult.

等を用いることができる。 The compound of the formula, which is a starting material, can be easily produced by reducing oxalate esters in recent years, and can be obtained with high purity by purification methods such as recrystallization. Examples of the alkyl group for the substituent R in the compound of formula include methyl group, ethyl group, propyl group, butyl group, and the like. Condensing agents include acids, preferably mineral acids such as hydrochloric acid, sulfuric acid, nitric acid, thiohalides such as chlorosulfonic acid, methanesulfonic acid chloride, benzenesulfonic acid chloride, thionyl chloride, sulfuryl chloride, inorganic alkalis such as caustic potash, caustic soda, Potassium carbonate, sodium hydrogen carbonate, etc., alcoholates such as sodium methylate, sodium ethylate, etc. can be used.
