实验步骤: To a solution of (4-fluoro-1-methylpiperidin-4-yl)methanol (0.265 g) in tetrahydrofuran (2 mL) was added sodium hydride (0.288 g). After 15 minutes, 3-chloro-4-fluorobenzenesulfonamide (0.377 g) was added as a solution in tetrahydrofuran (1 mL). The reaction was stirred for 2 hours, quenched with water (5 mL), adjusted to pH˜7 with 1N aqueous HCl, and extracted with dichloromethane (2×25 mL). The organic layer was washed with brine (25 mL), dried over magnesium sulfate, filtered and concentrated. Silica gel chromatography (Reveleris 40 g) eluting with a gradient of 0.1% to 10% methanol containing 2N NH3/dichloromethane over 30 minutes gave the title compound. quenched with water (5 mL) extracted with dichloromethane (2×25 mL) The organic layer was washed with brine (25 mL) dried over magnesium sulfate filtered concentrated Silica gel chromatography (Reveleris 40 g) eluting with a gradient of 0.1% to 10% methanol containing 2N NH3/dichloromethane over 30 minutes

实验步骤: To a solution of (4-fluoro-1-methylpiperidin-4-yl)methanol (0.315 g) in tetrahydrofuran (5 mL) was added sodium hydride (0.342 g). After stirring for 15 minutes, 4-fluoro-3-(trifluoromethylsulfonyl)benzenesulfonamide (0.658 g) was added as a solution in tetrahydrofuran (2 mL) followed by additional tetrahydrofuran (5 mL). After stirring for 1 hour, the reaction was poured in dichloromethane (50 mL) and water (25 mL) and the pH of the water layer was adjusted to 8. The organic layer was dried over magnesium sulfate, filtered, and concentrated. The resulting oil was chromatographed over silica gel (Reveleris 40 g) eluting with a gradient of 1.0% to 10% 7N NH3 in methanol/dichloromethane over 20 minutes then maintaining 10% 7N NH3 in methanol/dichloromethane for 5 minutes (flow=30 mL/min) to provide the title compound. After stirring for 1 hour The organic layer was dried over magnesium sulfate filtered concentrated The resulting oil was chromatographed over silica gel (Reveleris 40 g) eluting with a gradient of 1.0% to 10% 7N NH3 in methanol/dichloromethane over 20 minutes then maintaining 10% 7N NH3 in methanol/dichloromethane for 5 minutes (flow=30 mL/min)
