실험 절차

30 mg of (1RS,2RS,3E)-2-(3,4-dichlorobenzyl)-1-methyl-4-(2-naphthyl)-3-butenylamine was dissolved in 1 ml of methylene chloride, and 18 mg of mono-ethyl adipate, 12 mg of 4-dimethylaminopyridine and 19 mg of 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride were added thereto. The mixture was stirred at room temperature for 3 hours. The reaction solution was diluted with ethyl acetate, then sequentially washed with 1N hydrochloric acid, a saturated sodium hydrogencarbonate aqueous solution and a saturated sodium chloride aqueous solution, and dried over anhydrous sodium sulfate. The drying agent was separated by filtration, and then the solvent was distilled off under reduced pressure. The residue was dissolved in 1 ml of methanol, and then 0.5 ml of a 2N sodium hydroxide aqueous solution was added thereto. The mixture was stirred at room temperature for 2 hours. The reaction solution was concentrated under reduced pressure and then extracted by an addition of ethyl ether and 1N hydrochloric acid. The organic layer was washed with a saturated sodium chloride aqueous solution and then dried over anhydrous magnesium sulfate. The drying agent was separated by filtration, and then the solvent was distilled off under reduced pressure. The residue was subjected to silica gel thin layer chromatography (Kieselgel™ 60F254, Art 5744, manufactured by Merck Co.; chloroform/methanol=10/1) to obtain 21 mg (yield: 51%) of the above-identified compound as colorless oily substance.
