Reaction Steps

To a solution of 2-tert-butyl-5-(5-(4-chlorophenyl)-4-(2,2-dibromovinyl)-1-(2,4-dichlorophenyl)-1H-pyrazol-3-yl)-1,3,4-oxadiazole (230 mg, 0.36 mmol) in tetrahydrofuran (10 ml) at 78° C., potassium bis(trimethysilyl)amide (1.46 ml, 0.5 M solution in tetahydrofuran, 0.73 mmol) was added slowly. After stirring for 20 minutes at 78° C., the resulting solution was quenched with saturated ammonium chloride (5 ml). After warming up to room temperature, the solution was diluted with ethyl ether, and then the organic layer was extracted with ethyl acetate (50 ml twice). After evaporation, crude residue was purified with silica gel column (hexane/ethyl acetate=5/1) to obtain title compound (150 mg, 91% yield) as light yellow solid.
