Reaction Conditions

Temperature105 °C

Reaction Steps

A mixture of 1-(4-fluoropheny)-5-[4-(methylsulfonyl)phenyl]pyrazole-3-carbonitrile (1 g), ammonium chloride (0.25 g) and sodium azide (0.24 g) in N,N-dimethylformamide (10 ml) was stirred at 105° C. for 10 hours. The mixture was poured into ice-water, and the precipitates were collected, washed with water, and recrystallized from a mixture of ethanol and tetrahydrofuran to give crystals of 1-(4-fluorophenyl)-5-[4-(methylsulfonyl)phenyl]-3-(5-tetrazolyl)pyrazole (0.71 g).
