Procedure

To a solution of (1-(1,3-difluoropropan-2-yl)piperidin-4-yl)methanol (0.068 g) in tetrahydrofuran (1 mL) was added sodium hydride (0.056 g) and the reaction stirred for 30 minutes at room temperature. 4-Fluoro-3-nitrobenzenesulfonamide (0.077 g) was added in one portion and stirring was continued for 1 hour. The reaction was poured into water (20 mL) and extracted with dichloromethane. The pH of the aqueous layer was adjusted to pH˜8 and it was extracted with dichloromethane (50 mL). The organic layer was dried over magnesium sulfate, filtered, and concentrated to give the title compound.
