実験手順
8.01 g (31.2 mmol) of crude 2-(3-methoxy-4-benzyloxyphenyl)ethylamine, 3.78 g (37.4 mmol) of triethylamine and 80 ml of tetrahydrofuran were mixed and cooled to 0° C. and then (5,6,7,8-tetrahydronaphthalen-2-yl)acetyl chloride was added dropwise thereto. The mixture was stirred at 0° C. for 30 minutes and further at room temperature for 2 hours. Water was added to the reaction mixture, which was followed by extracted with ethyl acetate, washed with 5% hydrochloric acid and then saturated brine, dried over anhydrous magnesium sulfate and the solvent was distilled off under reduced pressure. The residue was subjected to silica gel column chromatography (eluent, hexane:ethyl acetate=1:1) to give 8.3 g of N-[2-(4-benzyloxy-3-methoxyphenyl)ethyl]-2-(5,6,7,8-tetrahydronaphthalen-2-yl)acetamide.
