Reaction Steps

At rt to a solution of 4:1 diastereomeric mixture (R)—N-(1-(3-fluoro-4-hydroxyphenyl)-1-(3-fluoro-5-(1,1,2,2-tetrafluoroethoxy)phenyl)-2-phenylethyl)-2-methylpropane-2-sulfinamide (578 mg, 1.06 mmol) in DMF (10 mL) was added K2CO3 (800 mg, 5.80 mmol) and the slurry was stirred vigorously. 2-Iodopropane (220 mg, 1.27 mmol) was added and the reaction mixture was stirred at rt for 16 h. The reaction mixture was diluted with ether (50 mL), washed successively with 10% LiCl (2×20 mL) and water (20 mL). The organic portion was dried over Na2SO4, filtered and concentrated to yield (R)—N-(1-(3-fluoro-4-isopropoxyphenyl)-1-(3-fluoro-5-(1,1,2,2-tetrafluoroethoxy)phenyl)-2-phenylethyl)-2-methylpropane-2-sulfinamide as a pale orange foam (780 mg, 100% yield).
