Procedure

tert-Butyl 6-[2-(dimethylamino)-2-oxoethyl]-1,4,5,6-tetrahydroazepino[4,5-b]indole-3(2H)-carboxylate (0.113 g, 0.305 mmol) was dissolved in CH2Cl2 (3 mL) at rt. CF3CO2H (1 mL) was added and the reaction mixture was stirred for 40 min. The reaction mixture was concentrated to give a crude product (0.145 g). The crude product was dissolved in EtOAc (3 mL), then 1 N HCl in Et2O (6 mL) was added and the precipitated salt was collected by filtration. N,N-Dimethyl-2-(2,3,4,5-tetrahydroazepino[4,5-b]indol-6(1H)-yl)acetamide hydrochloride (0.0896 g) was obtained in 95% yield. 1H NMR (300 MHz, CD3OD) δ 2.99, 3.14-3.17, 3.21-3.24, 3.26, 3.47-3.50, 5.16, 7.08, 7.15, 7.30, 7.50; MS (ESI+) for C16H21N3O m/z 272.2 (M+H)+.
