Procedure

A mixture of 5-chloro-N-((1-(4-iodophenyl)-1H-imidazol-4-yl)methyl)thiophene-2-carboxamide 1-6 (66 mg, 0.15 mmol), 5-fluoro-2-hydroxypyridine (46 mg, 0.40 mmol), 8-hydroxyquinoline (10 mg, 0.069 mmol) and K2CO3 (50 mg, 0.36 mmol) in DMSO (1 mL) was degassed with Ar before being charged with CuI (15 mg, 0.079 mmol). The mixture in a sealed tube was heated at 130° C. overnight. The mixture was then purified by HPLC to give the titled compound (6 mg). MS 429.0 and 431.0 (M+H, Cl pattern).
