반응 단계
N-methyl-1-naphthylmethylamine hydrochloride (2.1 g; 0.01 mole) was dissolved in 50 ml of dry dimethylformamide, and 3.71 g (0.035 mole) of anhydrous sodium carbonate was added. The mixture was stirred at room temperature, and 2.49 g (0.011 mole) of p-t-butylbenzyl bromide was added. The mixture was reacted at 30° to 40° C. for 5 hours. Ice water was added to the reaction mixture, and the mixture was extracted with toluene. The organic layer was washed with water, and toluene was evaporated. The residue was chromatographed on a silica gel column, and eluted with 5% ethyl acetate/n-hexane. The eluate was concentrated to give 2.98 g (yield 94%) of an oily substance.
