Procedure

In methanol (25 ml) and THF (30 ml) was dissolved methyl 7-(4-ethoxyphenyl)-1-formyl-2,3-dihydro-1H-1-benzazepine-4-carboxylate (0.24 g). To the solution was added 1N sodium hydroxide solution (5 ml) and the mixture was stirred at room temperature overnight and concentrated. To the residue was added water, and the mixture was 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, and the solvent was evaporated to give 7-(4-ethoxyphenyl)-1-formyl-2,3-dihydro-1H-1-benzazepine-4-carboxylic acid (0.23 g) as pale yellow crystals.
