Reaction Steps

A mixture of 5-chloro-N-((1-(4-iodophenyl)-1H-imidazol-4-yl)methyl)thiophene-2-carboxamide 1-6 (150 mg, 0.34 mmol), 3-methoxy-2-hydroxypyridine (85 mg, 0.68 mmol), 8-hydroxyquinoline (20 mg, 0.14 mmol) and K2CO3 (100 mg, 0.72 mmol) in DMSO (2 mL) was degassed with Ar before being charged with CuI (25 mg, 0.13 mmol). The mixture in a sealed tube was heated at 130° C. for 4 h. The mixture was then purified by HPLC to give the titled compound (99 mg). MS 441.0 and 443.0 (M+H, Cl pattern)
