実験手順

In 6.0 ml of chloroform was dissolved 0.69 g of 4-methoxyphenacyl bromide, and 3.0 ml of N-ethyldiisopropylamine and 1.20 g of 1-(4-naphthalen-1-yl-butyl)piperazine dihydrochloride were added, followed by reflux with heating for an hour. The reaction solution was cooled to room temperature, and concentrated under reduced pressure. To the residue was added a saturated aqueous sodium bicarbonate solution and, after extraction with ethyl acetate, the organic layer was dried over anhydrous sodium sulfate. After removal of the drying agent by filtration, the filtrate was concentrated under reduced pressure to give a crude 1-[2-(4-methoxyphenyl)-2-oxoethyl]-4-(4-naphthalen-1-yl-butyl)piperazine.
