Abstract

1417363 Imidazole - 4,5 - dicarboxamide NIPPON SODA CO Ltd 21 March 1974 [29 March 1973 4 April 1973] 12522/74 Heading C2C Imidazole-4,5-dicarboxamide is obtained (a) by reacting diaminomaleonitrile with aqueous formic acid of concentration 20-95% by weight, the mole ratio of formic acid to diaminomaleonitrile being at least 2 : 1 (e.g. 5 : 1 to 15 : 1), or (b) by reacting monoformyl diaminomaleonitrile with concentrated H 2 SO 4 and then mixing the resulting reaction mixture with water under cooling. Variant (a) is preferably effected at from 70‹ C. to the boiling point of the reaction solution for 1 to 30 hours and variant (b) is preferably carried out by reacting the c. H 2 SO 4 and monoformyl diaminomaleonitrile at - 5‹ to 0‹ C. for 5 to 6 hours and then allowing the reaction mixture to stand for 8 to 15 hours at 20‹ to 25‹ C. before mixing with the water.
