9-Ethyl-3-nitro-6,7,8,9-tetrahydro-5-oxa-9-aza-benzocycloheptene (0.865 g, 3.89 mmol) and 10% Palladium on Carbon (50% Wet) (0.400 g) in Ethanol (25 mL) were shaken under an atmosphere of Hydrogen (40 psi). After 2 h, the mixture was filtered through Celite, washing with ethanol. Conc. in vacuo afforded 9-Ethyl-6,7,8,9-tetrahydro-5-oxa-9-aza-benzocyclohepten-3-ylamine in quantitative yield. 1H-NMR (CDCl3): 6.75 (d, 1H, J=8.0 Hz), 6.32 (m, 2H), 4.04 (t, 2H, J=5.4 Hz), 3.43 (s, 2H), 3.09 (m, 4H), 1.96 (m, 2H), 1.14 (t, 3H, J=7.1 Hz).
