Reaction Steps

A mixture of 5-chloro-N-((1-(3-fluoro-4-iodophenyl)-1H-imidazol-4-yl)methyl)thiophene-2-carboxamide (83 mg, 0.14 mmol), 2-hydroxypyridine 1-7 (30 mg, 0.31 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 was heated at 130° C. in a sealed tube for 4 h. It was then purified by HPLC to give the titled compound (8 mg). MS 429.0 and 431.0 (M+H, Cl pattern).
