Procedure

To a mixture of 4-[2-(difluoromethyl)-1H-benzimidazol-1-yl]-6-morpholin-4-yl-N-(piperidin-4-ylmethyl)pyrimidin-2-amine (50 mg) and 1,2-dimethoxyethane (1 mL) were added bromobenzene (24 μL), tris(dibenzylideneacetone)dipalladium (0) (6.5 mg), dicyclohexyl(2′,4′,6′-triisopropylbiphenyl-2-yl)phosphine (11 mg), and potassium phosphate (96 mg), and the mixture was stirred in a microwave reactor at 130° C. for 1 hour. The reaction mixture was filtered through celite, and to the filtrate was added silica gel, followed by concentrating under reduced pressure. The residue was purified by silica gel column chromatography (hexane:ethyl acetate) to obtain 4-[2-(difluoromethyl)-1H-benzimidazol-1-yl]-6-(morpholin-4-yl)-N-[(1-phenylpiperidin-4-yl)methyl]pyrimidin-2-amine (39 mg) as a white powder.
