Reaction Steps

A mixture of 3-benzyl-6-ethyl-9-(phenylsulfonyl)-1,2,3,4,5,6-hexahydroazepino[4,5-b]indole (Step I, 107 mg, 0.241 mmol) in methanol (20 mL, 1 drop concentrated hydrochloric acid) is treated with palladium on carbon (10%, 32 mg) and hydrogenated at 25 psi for 48 hr. The resulting mixture is filtered, rinsing with methanol and methylene chloride, and the filtrate is concentrated to a solid. The solid is purified via chromatography (10 g SG; methanol/methylene chloride/ammonium hydroxide, 20/79/1) to give the title compound, mp=224°, dec.; IR (drift) 2982, 2935, 2743, 1473, 1449, 1312, 25 1300, 1151, 1091, 819, 768, 728, 691, 647 and 623 cm−1; NMR (300 MHz, DMSO-d6) 8.09, 7.85-7.95, 7.45-7.65, 4.20, 2.95-3.25 and 1.15 δ; MS (EI) m/z 354 (M+), 312, 170, 167, 153, 143, 114, 78, 76 and 51; HRMS (FAB) calculated for C20H23N2O2S=355.1480, found 355.1488.
