Procedure

Potassium carbonate (73.9 mg) was added to a mixture of 4-(2,2-dioxido-3,4,6,7,8,9-hexahydropyrido[2,1-c][1,2,4]thiadiazin-9-yl)phenol (50 mg) and 2-chloro-4-fluorobenzonitrile (41.6 mg) in DMF (dry) (1 mL). The mixture was stirred at 60° C. under atmosphere overnight. The mixture was quenched with water and extracted with EtOAc. The organic layer was separated, washed with water and brine, dried over anhydrous magnesium sulfate and concentrated in vacuo. The residue was purified by column chromatography (silica gel, eluted with MeOH in EtOAc) and concentrated. The residue was crystallized from MeCN-THF/IPE to give the title compound (32.2 mg) as colorless crystals.
