Reaction Steps
To a solution of Example 85E (1.45 g, 6.45 mmol) in DCM (50 mL) was added dropwise a solution of DIBAL (7.74 mL, 7.74 mmol, IM in toluene) at −78° C. under nitrogen. After stirring for 3 hours at −78° C., the reaction was quenched with saturated NH4Cl (10 mL) and the resulting mixture was extracted with dichloromethane (30 mLx2). The combined organic layers were washed with water (20 mL) and brine (20 mL), dried over Na2SO4, filtered, and concentrated. The residue was purified by column chromatography eluting with petroleum ether:EtOAc=100:1-100:3 to provide the title compound (733 mg, 3.2 mmol, 49% yield) as colorless oil. LC-MS: m/z 230 (M+H)+.
