実験手順

To a stirred solution of sodium (0.147 g, 6.41 mmol) in ethanol (20 ml) under nitrogen atmosphere was added 2-cyanoacetamide (539 mg, 6.41 mmol) and the mixture was refluxed 10 minutes. The mixture was cooled slightly, 3-(4-chlorobenzoyl)-4-chlorobenzyl azide (1.51 g, 4.93 mmol) was added, and the mixture was refluxed 1 hour. The mixture was cooled to 0° C. and filtered. The product was washed with ice cold ethanol (2×5 ml), water (3×5 ml), ice cold ethanol (2×5 ml), and diethyl ether (10 ml), and dried at 50° C. for 3 hours under vacuum to provide 1.16 g (60%) of 5-amino-1-(3-[4-chlorobenzoyl]-4-chlorobenzyl)-1,2,3-triazole-4-carboxamide, m.p. 189°-192° C.
