To a suspension of 4-[(9S)-2,2-dioxido-3,4,6,7,8,9-hexahydropyrido[2,1-c][1,2,4]thiadiazin-9-yl]phenol (1.00 g) and potassium carbonate (1.23 g) in DMF (dry) (30 mL) was added trifluoromethanesulfonyl chloride (0.939 mL) at 0° C. The mixture was stirred at 0° C. for 5 min then at room temperature for 2 hr. The mixture was added with water.
