Versuchsvorschrift

To a solution of methyl 3-[4-(2-butoxyethoxy)phenyl]-10-propyl-7,8,9,10-tetrahydropyrido[2,3-b]azocine-6-carboxylate (850 mg) in THF (30 ml) and methanol (30 ml) was added a 1 N aqueous sodium hydroxide solution (7.5 ml), and the mixture was heated at 90° C. for 3 hours. After cooling to 0° C., water was added thereto, and the mixture was neutralized with 1 N hydrochloric acid and extracted with ethyl acetate. The organic layer was washed with saturated brine, and dried over magnesium sulfate. The solvent was distilled off under reduced pressure and the resulting residue was washed with hexane to give 3-[4-(2-butoxyethoxy)phenyl]-10-propyl-7,8,9,10-tetrahydropyrido[2,3-b]azocine-6-carboxylic acid (739 mg) as yellow crystals.
