Reaction Steps

A mixture of 4-(3,3-difluoropiperidin-4-yl)phenol (200 mg, 0.94 mmol, E-2a from step D), 3-bromo-1-(4-(trifluoromethyl)benzyl)pyrrolidin-2-one (604 mg, 1.9 mmol), triethylamine (0.65 mL, 4.7 mmol), and 2 mL of DMF was heated in a microwave reactor at 120° C. for 1 h. The cooled reaction mixture was partitioned between water and 30 mL of ethyl acetate, and the aqueous phase was again extracted with 30 mL of ethyl acetate. The combined organic layers were dried over Na2SO4, filtered, and concentrated to afford 150 mg of 3-(3,3-difluoro-4-(4-hydroxyphenyl)piperidin-1-yl)-1-(4-(trifluoromethyl)-benzyl)pyrrolidin-2-one (0.33 mmol, 35%, 2 diastereoisomers) which was purified and separated in step F. LCMS (method J) RT 0.8 min (60% AP), m/z 455.4 (M+H+).
