Procedure

A mixture of (3,4,5-trifluorophenyl)boronic acid (1882 mg), 4-[(9S)-2,2-dioxido-3,4,6,7,8,9-hexahydropyrido[2,1-c][1,2,4]thiadiazin-9-yl]phenol (1000 mg), pyridine (7.21 mL), cesium carbonate (1162 mg), diacetoxycopper (1296 mg) and powdered 4A MS (10.0 g) in MeCN (36 mL) was stirred at room temperature overnight. The mixture was added with NH silica gel, concentrated in vacuo, and purified by column chromatography (NH silica gel, eluted with MeOH in EtOAc) then recrystallized from EtOAc to give the title compound (196 mg) as a white solid.
