Reaction Steps
The product of Step B (0.135 g) in dichloromethane (3 mL) was treated with pyridine (0.37 g) and cooled to 10° C. The cold solution was treated with methanesulfonyl chloride (0.112 g) and allowed to stir and warm to ambient temperature over 18 hours. The reaction mixture was washed with 1% H2SO4 solution, saturated sodium bicarbonate solution, dried over magnesium sulfate, filtered and evaporated to give the title compound (0.115 g).
