Hydrogenation of 1-(4-nitro-10-aza-tricyclo[6.3.1.02,7]dodeca-2(7),3,5-trien-10-yl)-2,2,2-trifluoro-ethanone (2.0 g, 6.66 mmol) under a hydrogen atmosphere (40 psi, or approximately 2.7 atmospheres) and 10% Pd/C (200 mg) in methanol over 1.5 hours, filtration through Celite and concentration affords a yellow oil (1.7 g). (TLC 50% ethyl acetate/hexanes Rf 0.27). 1H NMR (400 MHz, CDCl3) δ 6.99 (m, 1H), 6.64 (br s, 1H), 6.57 (m, 1H), 4.25 (m, 1H), 3.82 (m, 1H), 3.50 (m, 1H), 3.17–3.07 (m, 3H), 2.35 (m, 1H), 1.90 (d, J=10.8 Hz, 1H). GCMS m/e 270 (M+).
