Procedure

To a solution of the product of Step B (50 mg, 0.16 mmol) and N-methylmorpholine (32 mg, 0.32 mmol) in dichloromethane (2 mL) was added methanesulfonyl chloride (23 mg, 0.24 mmol) at room temperature. The mixture was stirred for 2 h, then diluted with water (15 mL) and extracted with ethyl acetate. The combined organic layers were washed with brine (10 mL), dried over Na2SO4, filtered and concentrated. The crude product was purified by PREP-TLC eluting with PE/EA (2/1, v/v) to give the title compound as a colorless solid. LC/MS m/z=391.0[M+H]+.
