Versuchsvorschrift

To a suspension of NaH (60%, 222 mg) in THF (dry) (20 mL) was added 2-chloroethanesulfonyl chloride (0.233 mL) at 0° C. and the mixture was stirred for 10 min at the same temperature. A solution of 3-(4-(4-fluoro-3-methoxyphenoxy)phenyl)-5-methylpyridin-2-amine (360 mg) in THF (dry) (20 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. Water, EtOAc and THF were added to the mixture and the organic phase was separated. Silica-gel was added to the organic phase and the volatiles were removed in vacuo. The mixture supported on silica-gel was purified by column chromatography (silica gel, eluted with MeOH in EtOAc) and concentrated in vacuo to give 9-[4-(4-fluoro-3-methoxyphenoxy)phenyl]-7-methyl-3,4-dihydropyrido[2,1-c][1,2,4]thiadiazine 2,2-dioxide as a white solid. This product was subjected to the next reaction without further purification. A part of the product was crystallized from EtOAc/IPE to give the title compound as a colorless solid.
