反応手順
A mixture of 4-(trifluoromethyl)phenylboronic acid (495 mg), 4-(2,2-dioxido-3,4-dihydropyrido[2,1-c][1,2,4]thiadiazin-9-yl)phenol (240 mg), diacetoxycopper (316 mg), triethylamine (0.60 mL), and powdered 4A MS (1.5 g) in DMF (10 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) to give the title compound (45 mg) as a white solid.
