methyl 13-cyclohexyl-7H-indolo[2,1-a][2]benzazepine-10-carboxylate → methyl 13-cyclohexyl-6,7-dihydro-5H-indolo[2,1-a][2]benzazepine-10-carboxylate

Reaction Steps

Method A: Palladium on carbon (60 mg of 10%) was added to a solution of Example 1 (60 mg, 0.16 mmol) in 60 mL of ethanol and 10 mL of ethyl acetate. The reaction vessel was flushed with H2. The resulting mixture was stirred at room temperature under an atmosphere of hydrogen (balloon pressure) for 4 hours. The mixture was filtered and concentrated to provide the desired product (60 mg, 100% yield) as a colorless solid. ESI-MS m/z 373 (MH+); 1H NMR (500 MHz, CDCl3) δ 1.22 (m, 1H), 1.39 (m, 2H), 1.65 (m, J=12.51 Hz, 1H), 1.76 (d, J=8.85 Hz, 2H), 1.91 (d, J=11.90 Hz, 1H), 1.91 (d, J=11.90 Hz, 1H), 2.06 (m, 3H), 2.38 (m, 1H), 2.56 (m, 1H), 2.68 (dd, J=13.43, 6.71 Hz, 1H), 2.91 (m, 1H), 3.70 (m, 1H), 3.97 (m, 3H), 4.43 (dd, J=14.34, 6.71 Hz, 1H), 7.35 (m, 4H), 7.73 (dd, J=8.54, 1.53 Hz, 1H), 7.87 (d, J=8.54 Hz, 1H), 8.08 (s, 1H).
