反応手順

To a suspension of methyl 2,7-dimethyl-1H-imidazo[4,5-b]pyridine-5-carboxylate (625 mg) in N,N-dimethylformamide (6 ml) was added sodium hydride (70% in mineral oil, 125 mg) under ice-cooling, and the mixture was stirred for 30 min. 1-Bromonaphthalen-2-ylmethyl bromide (1.05 g) was added to the reaction mixture, and the mixture was stirred under ice-cooling for 3 hr. Diisopropyl ether (12 ml) was added to the reaction mixture and the precipitate was collected by filtration to give the objective compound (1.35 g) as a white powder.
