Procedure

A mixture of 5-chloro-N-((1-(4-iodophenyl)-1H-pyrazol-4-yl)methyl)thiophene-2-carboxamide (200 mg, 0.451 mmol), 2-hydroxypyridine (85 mg, 0.90 mmol), 8-hydroxyquinoline (30 mg, 0.21 mmol) and K2CO3 (247 mg, 1.79 mmol) in DMSO (2 mL) was degassed with Argon before being charged with CuI (43 mg, 0.22 mmol). The mixture in a sealed tube was heated at 130° C. overnight. It was then purified by HPLC to give the title compound (60 mg). MS 411.0 and 413.0 (M+H, Cl pattern).
