Procedure

A stirred mixture of 4-methylbenzyl bromide (1.3 g, 7.0 mmol) and sodium azide (754 mg, 11.6 mmol) in ethanol (8 ml) was refluxed under a nitrogen atmosphere for 3 hours, cooled to ambient temperature, and filtered. Separately, 2-cyanoacetamide (588 mg, 7.0 mmol) was added to a stirred, refluxing solution of sodium (167 mg, 7.2 mmol) in ethanol (15 ml), followed by dropwise addition of the above azide solution over 20 min. The resulting slurry was PG,15 refluxed 1 hour, cooled to ambient temperature, and refrigerated. The precipitate was collected by filtration, washed with ethanol, and dried under vacuum to provide 1.12 g (69%) of 1-(4-methylbenzyl)-5-amino-1,2,3-triazole-4-carboxamide, m.p. 223°-225° C.
