Reaction Steps

Tetrakis(triphenylphosphine)palladium(0) (16.0 mg) was added to a mixture of (4-chlorophenyl)boronic acid (76.0 mg), 4-[(9S)-2,2-dioxido-3,4,6,7,8,9-hexahydropyrido[2,1-c][1,2,4]thiadiazin-9-yl]phenyl trifluoromethanesulfonate (100 mg) and sodium carbonate (51.4 mg) in EtOH (3 mL), water (1.5 mL) and DMF (dry) (2 mL). The mixture was stirred at 50° C. under nitrogen for 16 hr. Silica-gel was added and the volatiles were removed in vacuo. The mixture supported on silica-gel was purified by column chromatography (NH silica gel, eluted with MeOH in EtOAc) and crystallized from MeCN-THF/IPE to give the title compound (26.7 mg) as a colorless crystal.
