Oxamic acid hydrazide → 5-(2,6-difluorobenzyl)-4-methyl-4H-1,2,4-triazole-3-carboxamide

Participants

Reaction Steps

The reaction of 320 mg (1.5 mmol) of 1-ethoxy-2-(2,6-difluorophenyl)-1-(N-methylimino)-ethane and 155 mg (1.5 mmol) of oxalic acid monoamide monohydrazide can be carried out, in a manner analogous to that described in Example 1, but using 5 ml of N,N-dimethylformamide as solvent. 102 mg (27% of the theoretical yield) of 5-(2,6-difluorobenzyl)-4-methyl-4H-1,2,4-triazole-3-carboxamide of m.p. 186-189° are likewise obtained.
