Procedure

To a suspension of NaH (60%, 136 mg) in THF (dry) (10 mL) was added 2-chloroethanesulfonyl chloride (0.214 mL) at 0° C. and the mixture was stirred for 5 min at the same temperature. A solution of 3-{4-[(3-fluorobenzyl)oxy]phenyl}pyridin-2-amine (200 mg) in THF (dry) (10 mL) was added at 0° C. and the mixture was stirred at room temperature under nitrogen overnight. The mixture was quenched with water at 0° C. carefully. Water was added to form precipitates which were washed with water, hexane and collected. The precipitate was sonicated in EtOAc and the insoluble material was collected to give 9-{4-[(3-fluorobenzyl)oxy]phenyl}-3,4-dihydropyrido[2,1-c][1,2,4]thiadiazine 2,2-dioxide (317.7 mg) as an off-white solid. This was crystallized from MeOH-THF/IPE to give an off-white crystal.
