A mixture of 1,4-diiodobenzene 1-1 (4.00 g, 12.1 mmol), 4-(hydroxymethyl)imidazole II-1 (1.20 g, 12.2 mmol), 8-hydroxyquinoline (0.176 g, 1.21 mmol) and K2CO3 (1.69 g, 12.2 mmol) in DMSO (12 mL) was degassed before being charged with CuI (0.230 g, 1.21 mmol). The mixture in a sealed tube was heated at 130° C. overnight. Water and EtOAc were added. The mixture was filtered. The organic layer was separated, then applied to a silica gel column, which was eluted with 0-5% MeOH in CH2Cl2 to give 4-hydroxymethyl 1-(4-iodophenyl)imidazole I-1 (0.810 g). MS 301.2 (M+H).
