Reaction Steps

A solution of 0.18 g (0.001 mol) 5-phenyl-1H-1,2,4-triazole-3-acetonitrile in 7 ml tetrahydrofuran was treated at −70° C. with 1.56 ml (0.0025 mol) butyllithium (1.6 M in hexane). After one hour 0.21 g (0.001 mol) 3-bromo-3-phenyl-2-propenenitrile was added, stirring was continued for one hour, the mixture warmed to room temperature over night and water was added. Extraction with diethylether, chromatography on silicagel with dichloromethane/methanol 99/1 and crystallisation from diethylether gave 3.6 mg 5-amino-2,7-diphenyl-[1,2,4]triazolo[1,5-a]pyridine-8-carbonitril as white cystals. MS m/e (%): 312 (M+H+, 100).
