실험 절차

1,1-Dimethylethyl 7-hydroxy-8-nitro-1,2,4,5-tetrahydro-3H-3-benzazepine-3-carboxylate (8.2 g) was hydrogenated for 4 h under atmospheric pressure and 25° C. in the presence of 10% Pd/C (1.4 g) in EtOH (200 ml). The catalyst was removed by filtration and volatiles evaporated to provide the title compound as a grey solid (7.4 g).
