Reaction Steps

A mixture of 5-chloro-N-((1-(4-iodophenyl)-1H-imidazol-4-yl)methyl)thiophene-2-carboxamide 1-6 (56 mg, 0.10 mmol), 1,4-butanesultam (52 mg, 0.38 mmol), 8-hydroxyquinoline (6 mg, 0.040 mmol) and K2CO3 (50 mg, 0.36 mmol) in DMSO (1 mL) was degassed before being charged with CuI (10 mg, 0.052 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 (10 mg). MS 451.1 and 453.1 (M+H, Cl pattern).
