2-Phenylethynyl-3,4,5,6-tetrahydro-1H-azepino[5,4,3-cd]indol-6-one (Compound 17) (37 mg, 0.13 mmol) and platinum oxide (1.5 mg, 0.05 mmol) were suspended in 2 mL MeOH under an argon atmosphere. The flask was flushed with hydrogen gas and the resulting mixture stirred at 24° C. under 1 atmosphere of hydrogen for 20 h. The catalyst was filtered off and the resulting solution concentrated, leaving a pale-yellow crystalline solid. Purification by radial chromatography (5% MeOH in CHCl3) followed by recrystallization (MeOH/CHCl3/hexanes) yielded 2-phenethyl-1,3,4,5-tetrahydro-azepino[5,4,3-cd]indol-6-one, 14 mg (37%), as a pale-yellow solid. mp 207-208° C.; 1H NMR (300 MHz, d6-DMSO) δ 2.60 (m, 2H), 2.95 (m, 4H), 3.26 (m, 2H), 7.17 (m, 6H), 7.46 (dd, 1H, J=7.8, 0.6 Hz), 7.61 (dd, 1H, J=7.5, 0.6 Hz), 7.90 (br t, 1H), 11.16 (br s, 1H); MS (FAB, MH+) 291; Anal.
