130 °C

A mixture of 1,4-diiodobenzene 1-1 (4.00 g, 12.1 mmol), 2-hydroxypyridine 1-7 (1.15 g, 12.1 mmol), 8-hydroxyquinoline (176 mg, 1.21 mmol) and K2CO3 (1.74 g, 12.6 mmol) in DMSO (16 mL) was degassed with Ar before being charged with CuI (230 mg, 1.21 mmol). The mixture in a sealed tube was heated at 130° C. overnight. After being cooled to room temperature, H2O and EtOAc were added. It was filtered through celite. The organic phase was separated, dried over Na2SO4, concentrated in vacuo. The residue was purified by a silica gel column, eluted with EtOAc in hexanes (0-70% EtOAc) to give 1-(4-iodophenyl)pyridin-2(1H)-one (1.30 g).
