Procedure

A mixture of 4-bromo-1-(2-cyclopropyl-1-methyl-1H-benzimidazol-6-yl)pyridin-2(1H)-one (108 mg), ((2RS,3SR)-2-(4-chlorophenyl)-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)cyclopropyl)(trimethyl)silane (110 mg), potassium carbonate (130 mg), PdCl2(dppf) (11.5 mg), THF (6 ml) and water (2.0 ml) was heated at 70° C. overnight. The mixture was partitioned between water and EtOAc. The organic layer was washed with brine, dried over MgSO4, concentrated in vacuo, and purified by silica gel column chromatography (hexane/EtOAc) to give the title compound (26.0 mg) as a white solid.
