Procedure

Tert-butyl (6bS,11aS)-3-methyl-2,3,6b,7,8,10,11,11a-octahydro-1H,9H-azepino[4′,5′:4,5]pyrrolo[1,2,3-de]quinoxaline-9-carboxylate (115 mg, 0.33 mmol) was dissolved in 20% TFA (3 mL) in CH2Cl2 at rt. The reaction was stirred at rt for 2.5 hrs. Ice chips were added to the reaction, an then it was basified with 50% NaOH until pH=14. Brine (5 mL) was added and then the reaction was extracted with CH2Cl2 (2×10 mL). The combined organic layers were washed with brine, dried, and concentrated to afford the title compound (84.1 mg, 103%) as a viscous oil. 1H NMR (CDCl3, 300 MHz) δ 6.59–6.64 (1H, m), 6.48 (1H, d, J=7.3 Hz), 6.37 (1H, d, J=7.7 Hz), 3.4–3.7 (4H, m), 2.6–3.3 (10H, m), 1.7–2.2 (4H, m) ppm. MS (ESI): 244.2 (base, M+H)
