Procedure

4-(1-Methoxy-2-nitro-6,7,8,9-tetrahydro-5H-benzocyclohepten-7-yl)-morpholine (0.24 g, 0.00078 mol) was dissolved in ethanol (40 mL, 0.7 mol) and placed in a Parr bottle. To this solution was added palladium on carbon (10 mg). The reaction mixture was placed under 50 psi of hydrogen and shaken overnight. The mixture was filtered through celite and washed with additional ethanol (40 mL). The filtrate was concentrated in vacuo. The film was triturated with diethyl ether to provide 1-methoxy-7-morpholin-4-yl-6,7,8,9-tetrahydro-5H-benzocyclohepten-2-ylamine as a solid (0.21 g, 97%). 1H NMR (400 MHz, CDCl3) δ 6.71 (d, 1H, J=7.84 Hz), 6.51 (d, 1H, J=7.83 Hz), 3.70 (s, 7H), 3.31 (m, 1H), 2.75 (m, 1H), 2.60 (m, 2H), 2.55 (s, 4H), 2.31 (m, 1H), 2.0-2.16 (m, 2H), 1.37 (m, 2H).
