Procedure

A mixture of 4-chlorophenylboronic acid (407 mg), 4-(2,2-dioxido-3,4-dihydropyrido[2,1-c][1,2,4]thiadiazin-9-yl)phenol (240 mg), diacetoxycopper (316 mg), triethylamine (0.604 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 (132 mg) as a white solid.
