実験手順

A mixture of sodium carbonate (121 mg), tetrakis(triphenylphosphine)palladium(0) (13.18 mg), (4-phenoxyphenyl)boronic acid (98 mg) and 9-bromo-3,4-dihydropyrido[2,1-c][1,2,4]thiadiazine 2,2-dioxide (100 mg) in DMF (dry) (10 mL) and water (2 ml) was stirred at 80° C. under N2 overnight. NH silica gel was added and the mixture was concentrated in vacuo. The residue was purified by column chromatography (NH silica gel, eluted with MeOH in EtOAc) to give 9-(4-phenoxyphenyl)-3,4-dihydropyrido[2,1-c][1,2,4]thiadiazine 2,2-dioxide (116 mg) as a white solid. The solid was crystallized from DMSO (1.5 mL)-EtOH (3 mL) to give the title compound (90.7 mg) as a white solid.
