実験手順
To a -78° C. solution of 2-(3,5-Difluorophenyl)-3-(4-(methylsulfonyl)phenyl)-2-cyclopenten-1-one (98 mg, 0.28 mmol) in THF (5 mL) was added DIBAL (1.5M toluene solution, 0.4 mL, 0.6 mmol). The solution was warmed to 0° C. and stirred 15 min, then cooled to -78° C. and quenched with 0.5 mL acetone. The solution was warmed and poured into 1M sodium potassium tartrate. The mixture was extracted with EtOAc, washed with brine, and dried over MgSO4. Crystallization from ether/hexanes provided the title compound (90 mg).
