Reaction Steps

DIBAL-H (1.0M in hexanes, 1.5 mL, 1.5 mmol) was added dropwise at −78° C. to a stirred solution of 2-[1-(2-chlorophenyl)-5-{5-[3-(methylsulfonyl)phenyl]-2-thienyl}-1H-pyrazol-3-yl]-2-methyl propanenitrile (210 mg, 0.436 mmol) in dry DCM (10 mL) under N2, the resulting mixture was stirred at −78° C. for 3 h. At −78° C. 10% aqueous Rochelle's salt solution was added dropwise to quench the reaction, the mixture was allowed to warm to rt, and extracted with DCM. The combined extracts were washed with brine, dried over Na2SO4, and evaporated in vacuo. The crude product was purified by flash chromatography (0-60% 20% MeOH/DCM) to give the title compound as a white solid (160 mg, 76%). 1HNMR (CDCl3): δ 8.04 (m, 1H), 7.83-7.80 (m, 1H), 7.74-7.71 (m, 1H), 7.57-7.42 (m, 5H), 7.20 (d, 1H), 6.71 (d, 1H), 6.52 (s, 1H0, 3.07 (s, 3H), 2.90 (s, 2H), 2.17 (brs, 2H), 1.39 (s, 6H). MS(ES): 486 [M+H]+.
