Reaction Steps

To ethyl (6bR,10aS)-2,3,6b,9,10,10a-hexahydro-1H-pyrido[3′,4′:4,5]pyrrolo[1,2,3-de]quinoxaline-8(7H)-carboxylate (4.10 g, 14.3 mmol) was added n-butanol (18.0 mL) and KOH powder (3.0 g). The reaction was heated at 199° C. in a sealed tube for 18 hr. The solvent was removed under reduced pressure. To the residue was added water (30 mL) extracted with CH2Cl2 (3×50 mL). The combined organic layers were washed with brine, dried over MgSO4, and concentrated to afford the title compound as a pale yellow oil (2.70 g, 78%). MS-ESI: 216 [MH]+
