실험 절차

To methyl 8-(4-(2-butoxyethoxy)phenyl)-1-isobutyl-9-methyl-1,2,3,4-tetrahydro-1-benzoazocine-5-carboxylate (770 mg) were added tetrahydrofuran (15 ml) and methanol (15 ml), followed by adding aqueous 1N sodium hydroxide solution (4.8 ml), and the mixture was stirred at 90° C. overnight. After cooling to 0° C., water was added and the mixture was neutralized with 1N hydrochloric acid. After extracting with ethyl acetate, the organic layer was washed with saturated brine, and dried with magnesium sulfate. The solvent was distilled off under reduced pressure, and the resulting residue was recrystallized from hexane-ethyl acetate to give 8-(4-(2-butoxyethoxy)phenyl)-1-isobutyl-9-methyl-1,2,3,4-tetrahydro-1-benzoazocine-5-carboxylic acid (408 mg) as yellow crystals.
