実験手順

Tetrakis(triphenylphosphine)palladium(0) (16 mg) was added to a mixture of (3-chloro-4-fluorophenyl)boronic acid (85 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), dissolved in MeCN/DMSO (2500/300 μM) and purified by preparative HPLC (C18, eluted with water in acetonitrile containing 0.1% TFA). The desired fractions were neutralized with sat. NaHCO3 aq., extracted with EtOAc and washed with brine. The organic layer was separated, dried over anhydrous magnesium sulfate and concentrated in vacuo to give the title compound (20 mg) as a white solid.
