Imidazole → N-p-methoxybenzylimidazole

Participants

Reaction Steps

To a stirred solution of imidazole (25.53 g, 375 mmole) in acetonitrile (625 ml) was added p-methoxybenzyl chloride (16.95 ml, 125 mmole). The reaction was refluxed for 16 hours, evaporated to dryness, and redissolved in methylene chloride and saturated sodium bicarbonate. The organic layer was extracted with water twice. Standard acid/base workup gave N-p-methoxybenzylimidazole (16.3 g, 69%) which was used without further purification:
