Procedure

To a solution of 2-(9-chloro-3-methyl-2,3,4,5-tetrahydroazepino[4,5-b]indol-6(1H)-yl)-1-(3,4-dimethoxyphenyl)ethanol (300 mg, 0.722 mmol) in DCM (5 mL), triethylamine (0.15 mL, 1.077 mmol) were added and stirred for 10 min., methane sulfonyl chloride (0.062 mL, 0.795 mmol) was added slowly at 0° C. and stirred at the same temperature for 1 h, then at RT for 2 h. Reaction mixture was diluted with water, extracted with dichloromethane. The organic layer was dried over anhydrous sodium sulfate and evaporated under reduced pressure. The crude product was purified by column chromatography. The pure product was dissolved in NMP (2.0 mL), KOH powder (283 mg, 5.06 mmol) was added at RT and heated at 90° C. for 14 h. Product was detected by LCMS. The reaction mixture was diluted with methanol, filtered and evaporated. Crude product was purified by reverse phase chromatography to get 18 mg of pure product as TFA salt. 1H NMR (DMSO-d6, TFA salt) δ (ppm): 7.80-7.60 (m, 2H), 7.35 (s, 1H), 7.30-7.20 (d, 1H), 7.20-7.15 (d, 1H), 7.00-6.90 (d, 1H), 6.80-6.70 (m, 2H), 3.90 (s, 3H), 3.85 (s, 3H), 3.80-3.60 (m, 2H), 2.95 (s, 3H), 2.90-2.80 (m, 2H), 2.60-2.30 (m, 4H).
