Procedure
To a solution of 0.158 g the intermediate from Step B in 5 mL of dichloromethane was added 0.053 mL of N-methylmorpholine, and 0.034 mL of ethanesulfonylchloride and stirred at 0° C. for 30 min and RT for 1 h. The reaction mixture was diluted with an additional 5 mL of dichloromethane and washed with 5 mL of saturated sodium bicarbonate solution, brine (5 mL), dried over MgSO4 and concentrated. Flash chromatography of the residue over 10 g of silica gel with CH2Cl2 -ether (3:1) as eluent gave 0.057 g of the desired product.
