Procedure

A mixture of 4-(tert-butyldimethylsilyloxy)phenylboronic acid (6.11 g), 4-(2,2-dioxido-3,4-dihydropyrido[2,1-c][1,2,4]thiadiazin-9-yl)phenol (2.23 g), triethylamine (5.61 mL), diacetoxycopper (2.93 g), and 4A MS (2.0 g) in DMF (80 mL) was stirred at room temperature overnight. The mixture was added with silica gel, concentrated in vacuo, and purified by column chromatography (silica gel, eluted with EtOAc in hexane) to give the title compound (1.82 g) as a white solid.
