Reaction Steps

A mixture of the 3-bromomethyl-1-(2-chlorophenyl)-5-{5-[3-(methylsulfonyl)phenyl]-thiophen-2-yl]-1H-pyrazole (720 mg, 1.42 mmol), NaCN (250 mg, 5.1 mmol), and DMSO (10 mL) was stirred in a sealed vial at 100° C. for 5 h, diluted with water, and extracted with EtOAc. The combined extracts were washed with water, brine, dried over Na2SO4, and evaporated in vacuo. The crude product was purified by flash chromatography (0-80% EtOAc/hexanes) to give the title compound as a white solid (350 mg, 54%). 1HNMR (CDCl3): δ 8.03 (d, 1H), 7.84 (m, 1H), 7.72 (m, 1H), 7.58-7.44 (m, 5H), 7.22 (d, 1H), 6.79 (d, 1H), 6.73 (s, 1H), 3.87 (s, 2H), 3.09 (s, 3H). MS(ES): 454 [M+H]+.
