Procedure

A mixture of 1-(4-iodo-3-(2-(piperidin-1-yl)ethoxy)phenyl)pyridin-2(1H)-one (116 mg, 0.22 mmol), N-((1H-imidazol-4-yl)methyl)-5-chlorothiophene-2-carboxamide 3-1 (85 mg, 0.24 mmol), 8-hydroxyquinoline (14 mg, 0.10 mmol) and K2CO3 (200 mg, 1.45 mmol) in DMSO (3 mL) was degassed with Ar before being charged with CuI (19 mg, 0.10 mmol). The mixture in a sealed tube was heated at 130° C. overnight. It was then purified by HPLC to give the titled compound (10 mg). MS 538.2 and 540.2 (M+H, Cl pattern).
