実験手順
A solution of 8-cyclohexyl-3-(4-nitrophenyl)-8-azabicyclo[3.2.1]oct-2-ene (230 mg; 0.74 mmol; 1.0 eq.) in EtOH (7 mL) was passed twice at 1 mL/min through the H-Cube using a cartridge of Pd/C under full H2 at 250. The solution was then concentrated under reduced pressure to give the title compound as a 66:33 mixture of the endo:exo isomers (163 mg; 78%). 1H NMR (DMSO) δ 6.94 (d, J=8.3 Hz, 1.3H), 6.87 (d, J=8.3 Hz, 0.7H), 6.48-6.45 (m, 2H), 4.78 (bs, 2H), 3.47 (m, 2H), 2.84-2.70 (m, 1H), 2.19-2.07 (m, 2H), 1.90-1.82 (m, 3H), 1.72-1.63 (m, 5H), 1.54-1.46 (m, 2H), 1.40-1.33 (m, 2H), 1.27-0.98 (m, 5H). HPLC (max plot) 65.3%; Rt %2.25 min. UPLC/MS: (MS+) 285.4.
