3-(2-Fluoro-1-fluoromethyl-ethyl)-7-methoxy-8-nitro-2,3,4,5-tetrahydro-1H-benzo[d]azepine (670 mg, 2.23 mmol) was dissolved in methanol (40.0 mL, 987 mmol) and 10% Palladium on Carbon (50% Wet) (5:45:50, Palladium:carbon black:Water, 240 mg) was added. The reaction was hydrogenated at 35 psi. for 1 hour. The reaction was filtered through Celite and concentrated under reduced pressure to obtain 3-(2-fluoro-1-fluoromethyl-ethyl)-8-methoxy-2,3,4,5-tetrahydro-1H-benzo[d]azepin-7-ylamine as a green oil (603 mg, 100%). LCMS (m/e) 271 (M+H); 1H-NMR (CDCl3, 400 MHz) δ 6.58 (s, 1H), 6.51 (s, 1H), 4.75-4.66 (m, 2H), 4.64-4.54 (m, 2H), 3.84 (s, 3H), 3.67 (bs, 2H), 3.27-3.09 (m, 1H), 2.90-2.75 (m, 8H).
