Triethylamine → N-methyl-N-(4'-isopropylbenzyl)-1-naphthylmethylamine

反応手順

1.71 g (0.01 mole) of N-methyl-1-naphthylmethylamine was dissolved in 30 ml of tetrahydrofuran, and 1.2 g (0.012 mole) of triethylamine was added. With stirring at room temperature, 1.85 g (0.011 mole) of p-isopropylbenzyl chloride was added, and the mixture was reacted at room temperature for 6 hours. The reaction mixture was filtered, and the solvent was removed under reduced pressure. The residue was distributed between ether and a saturated aqueous solution of sodium hydrogen carbonate, and the organic layer was collected. The organic layer was washed with water, dried over sodium sulfate and then concentrated under reduced pressure. The residue was chromatographed on a silica gel column and eluted with 4% ethyl acetate/n-hexane. The eluate was concentrated to give 2.82 g (yield 93%) of an oily substance.
