Reaction Steps

Under nitrogen atmosphere, sodium cyanide (540 mg) was added to a solution of 4-chloromethyl-1-tritylpyrazole (3.58 g) in dimethylsulfoxide (30 ml) at 50° C. After stirring for 1 hour, the mixture was poured into water. The organic layer was separated, washed with water and brine, and dried over magnesium sulfate. The solvent was evaporated, to afford 4-cyanomethyl-1-tritylpyrazole (3.41 g).
