실험 절차

7-(4-Methoxycarbonyl-benzyloxy)-1,2,4,5-tetrahydro-benzo[d]azepine-3-carboxylic acid tert-butyl ester (D3) (6.35 g) was dissolved in dichloromethane (30 ml) and treated with trifluoroacetic acid (30 ml). The solution was stirred at room temperature for 2 hours, concentrated in vacuo and then twice co-evaporated with dichloromethane. The residue was dissolved in dichloromethane and washed with 10% aqueous sodium hydroxide, water and brine. The organic layer was dried over magnesium sulfate, filtered and concentrated in vacuo to afford the title compound (D4).
