Versuchsvorschrift

The product of Step A (0.33 g) in dichloromethane (20 mL) was treated with triethylamine ( 0.36 g) and cooled to 0° C. The cold solution was treated with methanesulfonyl chloride (0.338 g) and allowed to stir and warm to ambient temperature over 18 hours. The reaction mixture was washed with water (50 mL), saturated sodium bicarbonate solution (25 mL), water (50 mL), dried over sodium sulfate, filtered and evaporated to give the crude title compound (0.53 g). The crude product was used, Step C, without further purification.
