Reaction Conditions

Temperature	130 °C

Reaction Steps

A mixture of 1-(4-iodophenyl)pyridin-2(1H)-one prepared in Example 19 (1.00 g, 3.37 mmol), 4-hydroxymethylimidazole II-1 (0.330 g, 3.37 mmol), 8-hydroxyquinoline (0.073 g, 0.50 mmol) and K2CO3 (1.00 g, 7.25 mmol) in DMSO (7 mL) was degassed with Ar before being charged with CuI (0.100 g, 0.52 mmol). The mixture in a sealed tube was heated at 130° C. overnight. Water and EtOAc were added. The mixture was filtered through CELITE. The organic layer was separated, dried over Na2SO4, concentrated in vacuo. The residue was purified by HPLC to give 1-(4-(4-(hydroxymethyl)-1H-imidazol-1-yl)phenyl)pyridin-2(1H)-one (335 mg). MS 268 (M+H).
