実験手順

In methanol (25 ml) and THF (25 ml) was dissolved methyl 7-[4-(2-butoxyethoxy)phenyl]-1-cyclobutylmethyl-2,3-dihydro-1H-1-benzazepine-4-carboxylate (0.47 g). To the solution was added 1N sodium hydroxide solution (10 ml), and the mixture was heated at 50° C. overnight, concentrated, neutralized with 1N hydrochloric acid and extracted with ethyl acetate. The organic layer was washed with water and saturated brine and dried with anhydrous magnesium sulfate. The solvent was evaporated to give 7-[4-(2-butoxyethoxy)phenyl]-1-cyclobutylmethyl-2,3-dihydro-1H-1-benzazepine-4-carboxylic acid (0.40 g) as yellow crystals.
