2,2,2-Trifluoro-1-(4-nitro-10-aza-tricyclo[6.3.2.0*2,7*]trideca-2,4,6-trien-10-yl)-ethanone (1.227 g, 3.91 mmol) was placed in methanol (100 mL) and acetic acid (1 mL). 10% Palladium on carbon (6.8 mg) was then added. The reaction was hydrogenated at 20 psi for 30 minutes. The mixture was then filtered through celite and concentrated under reduced pressure to obtain 1-(4-amino-10-aza-tricyclo[6.3.2.0*2,7*]trideca-2,4,6-trien-10-yl)-2,2,2-trifluoro-ethanone as a brown oil (1.110 g, 100%). LCMS (m/e) 285 (M+1); 1H-NMR (CDCl3, 400 MHz) δ 6.92 (dd, 1H, J=8.0 and 10.9 Hz), 6.60-6.50 (m, 2H), 4.23-4.10 (m, 1H), 3.90-3.75 (m, 1H), 3.46-3.25 (m, 2H), 3.15-3.00 (m, 2H), 2.03-1.91 (m, 2H), 1.80-1.70 (m, 2H).
