Participants

Reaction Steps

Iodomethane (2 M in methyl-text-butyl ether, 22.87 mL, 45.7 mmol) was added to a solution of cesium carbonate (14.9 g, 45.7 mmol) and 1-(biphenyl-4-ylmethyl)-4,6-difluoro-5-iodo-1,3-dihydro-2H-benzimidazole-2-thione (10.94 g, 22.87 mmol) in THF (100 mL). After stirring at rt. overnight, volatiles were removed. Chromatography over silica eluting with 15-60% EtOAc/hexanes afforded the desired product as a beige solid.
