Versuchsvorschrift

To a solution of sodium hydride (46 mg, 1.16 mmol) in THF (5 ml), 3,9-dimethyl-1,2,3,4,5,6-hexahydroazepino[4,5-b]indole (0.1 g, 0.46 mmol) was added at 0° C. and stirred at RT for 30 min. tert-Butyl 4-(2-chloroacetyl)piperazine-1-carboxylate (147 mg, 0.55 mmol) was added slowly dropwise at RT and stirred for 2 h at RT. After completion of the reaction (monitored by TLC & LCMS), the reaction was quenched with ice water and extracted with ethyl acetate. The organic layer was washed with brine, dried over anhydrous sodium sulfate and evaporated under reduced pressure. Crude product was purified by column chromatography to afford free base, which was converted to HCl salt using ethanolic HCl (38 mg). The NMR confirmed removal of the Boc group when ethanolic HCl was used. 1H NMR (CD3OD, DiHCl salt) δ (ppm): 7.3 (s, 1H), 7.22 (d, 1H), 7.0 (d, 1H), 5.23 (d, 2H), 3.95-4.10 (m, 4H), 3.7-3.9 (m, 4H), 3.36-3.43 (m, 4H), 3.1-3.22 (m, 4H), 3.0 (s, 3H), 2.4 (s, 3H).
