A mixture of 6-bromo-1,2-dimethyl-1H-benzimidazole (500 mg), 4-((4-fluorobenzyl)oxy)pyridin-2(1H)-one (487 mg), CuI (423 mg), N,N′-dimethyl-1,2-ethanediamine (0.236 ml), potassium carbonate (921 mg) and DMSO (10 ml) was stirred at 150° C. for 1 h. 28% NH3 solution was added to the resulting mixture, and the solid was washed with water. The solid was purified by NH silica gel column chromatography (hexane/EtOAc), followed by recrystallization from EtOAc-hexane to give the title compound (200 mg) as a white solid.
