Reaction Steps

2.6 g. of 1-ethyl-4-hydrazino-6-methyl-1H-1,2,3-triazolo[4,5-c]pyridine-7-carboxylic acid ethyl ester (0.01 mol.) are dissolved in 10 ml. of acetone. One drop of acetic acid is added and the mixture is allowed to stand overnight. The excess acetone is distilled off in vacuo and the residue is recrystallized from petroleum ether to obtain 1-ethyl-6-methyl-4-[2-(1-methylethylidene)hydrazino]-1H-1,2,3-triazolo[4,5-c]pyridine-7-carboxylic acid ethyl ester in 95% yield, m.p. 68°-72°.
