Procedure

A mixture of 4 parts of N-(4-nitrophenyl)hydrazinecarboxamide, 5 parts of ethanimidamide hydrochloride and 5 parts of sodium acetate is stirred and heated for 4 hours at 140° C. The reaction mixture is cooled, water is added and the whole is stirred till the product is crystallized. It is filtered off and recrystallized from 2-propanol, yielding 1.5 parts (34%) of 2,4-dihydro-5-methyl-4-(4-nitrophenyl)-3H-1,2,4-triazol-3-one; mp. 226.1° C.
