Participants

Reaction Steps

A mixture of (3-chloro-4-fluorophenyl)boronic acid (933 mg), 4-[(9S)-2,2-dioxido-3,4,6,7,8,9-hexahydropyrido[2,1-c][1,2,4]thiadiazin-9-yl]phenol (500 mg), pyridine (3.60 mL), cesium carbonate (581 mg), diacetoxycopper (648 mg) and powdered 4A MS (4 g) in MeCN (18 mL) was stirred at room temperature for 3 days. The mixture was added with NH silica gel, concentrated in vacuo, and purified by column chromatography (NH silica gel, eluted with MeOH in EtOAc) then recrystallized from EtOAc-THF/IPE to give (9S)-9-[4-(3-chloro-4-fluorophenoxy)phenyl]-3,4,6,1,8,9-hexahydropyrido[2,1-c][1,2,4]thiadiazine 2,2-dioxide (290.6 mg) as a white solid.
