実験手順
In methanol (5 ml) was suspended 7-(3,4-methylenedioxy-phenyl)-2,3-dihydro-1-benzoxepine-4-carboxylate (399 mg, 1.23 mmol), and to the mixture was added 1N sodium hydroxide solution (3.69 ml). The mixture was stirred at room temperature for 20 hours, and to the mixture was added 1N hydrochloric acid (3.69 ml). The mixture was concentrated under reduced pressure, and to the residue was added water. Insoluble materials were filtered, which were washed with water and diethylether and dried under reduced pressure to give 7-(3,4-methylenedioxyphenyl)-2,3-dihydro-1-benzoxepine-4-carboxylic acid(321 mg, 1.03 mmol, 84%).
