Versuchsvorschrift

Diacetoxycopper (907 mg) was added to a mixture of pyridine (0.606 mL), 2-chloro-5-(trifluoromethyl)phenylboronic acid (459 mg), 4-[(9S)-2,2-dioxido-3,4,6,7,8,9-hexahydropyrido[2,1-c][1,2,4]thiadiazin-9-yl]phenol (700 mg) and cesium carbonate (814 mg) in MeCN (25 mL). 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 brine and 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) and concentrated in vacuo to give the title compound (5.9 mg) as pale yellow gum.
