Reaction Steps

To a solution of tert-butyl (±)-5,6,8,9,10,11,12,12a-octahydro-4H,7aH-azepino[4′,5′:4,5]pyrrolo[3,2,1-ij]quinoline-10-carboxylate in CH2Cl2 (2.4 mL) was added TFA (0.6 mL). This was stirred at 20° C. for 3 h. The reaction mixture was diluted with CH2Cl2 (50 mL) and washed with saturated NaHCO3 (50 mL) and brine (50 mL), dried over MgSO4 and concentrated in vacuo to afford the title compound as a yellow oil (87 mg, 59%). 1H NMR (CDCl3, 300 MHz) δ 1.77-2.13 (m, 7H), 2.56-2.79 (m, 5H), 2.83-2.93 (m, 1H), 3.00-3.16 (m, 2H), 3.33-3.41 (td, 1H, J=3.7, 9.2 Hz), 3.60 (td, 1H, J=4.4, 9.1 Hz), 6.50 (t, 1H, J=7.3 Hz), 6.76 (t, 2H, 8.0 Hz) ppm.
