Reaction Steps

To a solution of 2-(2-bromo-4-chloro-phenyl)-1-cyclohexylmethyl-5,6-difluoro-1H-benzoimidazole (600 mg, 1.36 mmol) in tetrahydrofuran (20 ml) was added 4-ethynyl-benzonitrile (173.4 mg, 1.36 mmol; CAS Reg. No. 3032-92-6), bis(triphenylphosphine)palladium(ii) dichloride (57.2 mg, 0.08 mmol), copper iodide (7.7 mg, 0.04 mmol) and triethyl amine (20 ml) at 25° C. The resulting mixture was degassed and back-filled with nitrogen three times. It was then allowed to stir at 80° C. for 16 h. The reaction mixture was filtered through a bed of celite and solvents were removed under reduced pressure. The residue was purified by column chromatography over silica gel (10% ethyl acetate/n-hexane) to afford the desired compound as a yellow solid (18%). MS (Turbo Spray): m/z=485.6 (M+H).
