Reaction Steps

To a solution of 1--(3-biphenylyl)-5-hydroxymethylbenzimidazole (61a) (0.16 g, 0.5 mmol) in dry DMF (1.5 ml) under nitrogen, was added a 80% sodium hydride suspension (20 mg, 0.7 mmol) and then iodomethane (33.5 μl, 0.5 mmol). The reaction mixture was stirred overnight and then poured in water. Neutralization with 4M aqueous HCl was followed by extraction with ethyl acetate. The extract was evaporated to dryness and purified by chromatography. The product was dissolved in dry ether and precipitated as the hydrochloride. Yield: 130 mg, 0.4 mmol, 80%. mp 70°-72° C.
