Reaction Conditions

Reaction Steps

Sodium hydride (0.1 g) was taken in dry DMF (2 ml) and a solution of tert-butyl 4-(3-phenyl-1H-pyrazol-4-yl)piperazine-1-carboxylate (0.5 g in 2 ml of DMF) was added slowly at 0° C. The reaction mixture was stirred for 30 min at 0° C. and a solution of chloroacetonitrile (0.138 g) in DMF (1 ml) was added very slowly. The reaction mixture was allowed to stir over night at room temperature. The reaction mixture was quenched with cold water (5 ml) and extracted with ethyl acetate (3×40 ml). Evaporation of solvent under reduced pressure gave crude product, which, was purified by column chromatography using ethyl acetate\hexane (2:8) as eluent to afford tert-butyl 4-(1-(cyanomethyl)-3-phenyl-1H-pyrazol-4-yl)piperazine-1-carboxylate as pure solid product.
