实验步骤: To a solution of EXAMPLE 296C (0.175 g) in tetrahydrofuran (5 ml) was added sodium hydride (0.209 g) and the reaction stirred at room temperature for 15 minutes. 3-Chloro-4-fluorobenzenesulfonamide (0.273 g) was added and the reaction stirred for 3 hours. To the thick suspension was added tetrahydrofuran (2 ml) and N,N-dimethylformamide (3 ml). The reaction was stirred for 3 hours at 60° C. then poured into dichloromethane (50 ml) and 1N aqueous HCl (50 ml). The organic layer was washed with brine (35 ml) dried over magnesium sulfate, filtered, and concentrated. Silica gel chromatography (Reveleris 40 g) eluting with a gradient of 10-100% ethyl acetate/hexanes over 30 minutes (flow=40 ml/minute) gave the title compound. the reaction stirred for 3 hours The reaction was stirred for 3 hours at 60° C.

实验步骤: To a solution of EXAMPLE 37C (0.500 g) in tetrahydrofuran (5 mL) was added sodium hydride (0.596 g). Additional tetrahydrofuran (25 mL) was added and the mixture stirred for 30 minutes, then 4-fluoro-3-(trifluoromethylsulfonyl)benzenesulfonamide (1.145 g) was added as a solution in tetrahydrofuran (5 mL). After stirring for 2 hours, the reaction mixture was partioned between 1N aqueous HCl (50 mL) and dichloromethane (200 mL). The organic layer was dried over magnesium sulfate, filtered, and concentrated. The resulting solid was chromatographed over silica gel (Reveleris 80 g) eluting with a gradient of 0.5% to 7.5% methanol/dichloromethane over 30 minutes (flow=40 mL/min) to provide the title compound.
