Procedure

To a suspension of 2-cyanoacetamide (527 mg, 6.27 mmol) in ethanol (20 ml) was added sodium methoxide (330 mg, 6.11 mmol). The mixture was refluxed 15 minutes, cooled slightly, and 4-(4-chlorobenzoyl)benzyl azide (1.24 g, 4.56 mmol) was added. The mixture was refluxed 2 hours, cooled to ambient temperature, and filtered. The filtrate was evaporated under vacuum and the residue was triturated with hot 19:1 (v/v) dichloromethane-methanol (50 ml) and filtered. The remaining solid was triturated with hot methanol (3 ml), filtered, and dried at 60° C. under vacuum to provide 182 mg (11%) of 5-amino-1-(4-[4-chlorobenzoyl]benzyl)-1,2,3-triazole-4-carboxamide, m.p. 229°-231° C.
