実験手順

6-acetoxy-2-oxo-2,3,4,5-tetrahydro-1H-1-benzoazepine (252 mg) was dissolved in DMF (5 ml), and the resultant solution was stirred at room temperature. Potassium carbonate (509 mg) and methyl bromoacetate (0.22 ml) were added to the solution at room temperature. After disappearance of the raw materials was confirmed, water (20 ml) was added to the reaction solution, and the mixture was then extracted with ethyl acetate. The resultant organic layer was washed with saturated saline, dried over anhydrous sodium sulfate, and then concentrated. The resultant residue was purified by column chromatography (silica gel:hexane/ethyl acetate=1/1) to obtain the object compound ml (333 mg, yield 99%).
