Reaction Steps

Sodium hydride (60% in mineral oil, 404 mg, 10.09 mmol) was added to an ice-cold solution of EXAMPLE 33A (2.35 g, 8.41 mmol) in anhydrous DMF (20 mL) under nitrogen. The reaction mixture was stirred at 0° C. for 30 minutes and benzenesulfonyl chloride (1.19 mL, 9.25 mmol) was then added. The ice-bath was removed and the mixture was stirred at room temperature overnight. This reaction was quenched with the addition of 50 mL of water. An off white solid material was collected by filtration, washed with water and hexane, and dried to give 3.38 g of the title product. Yield: 96%. MS (DCI+) m/z 280 (M+H)+.
