실험 절차

Diacetoxycopper (1037 mg) was added to a mixture of triethylamine (1.983 mL), 4-chlorophenylboronic acid (1339 mg), 4-[(9S)-2,2-dioxido-3,4,6,7,8,9-hexahydropyrido[2,1-c][1,2,4]thiadiazin-9-yl]phenol (800 mg) and in DMF (dry) (30 mL). The mixture was stirred at room temperature under a dry atmosphere with anhydrous calcium chloride tube for 15 hr. Then 4-chlorophenylboronic acid (1339 mg) and diacetoxycopper (1037 mg) were added and the mixture was stirred at room temperature under a dry atmosphere with anhydrous calcium chloride tube for 2 days. The insoluble material was removed by filtration, and the filtrate was diluted with water, and extracted with EtOAc. The organic layer was washed with 0.1N NaOH aq., dried over anhydrous magnesium sulfate. 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) then crystallized from THF/IPE to give the title compound (177 mg) as an off-white solid.
