Procedure

A solution of EXAMPLE 263E (2.0 g) and diethylaminosulfur trifluoride (1.39 mL) in dichloromethane (40 mL) was stirred for 24 hours. The reaction was quenched with water (30 mL), extracted twice with ether, and the combined extracts were washed with water, and brine, dried over Na2SO4, filtered, and concentrated. The crude product was chromatographed on silica gel using 5% ethyl acetate in hexanes to provide the title compound.
