Reaction Steps

The title compound was prepared by following general procedure 5. To a stirred suspension of sodium hydride (94 mg, 3.92 mmol) in 5 mL of DMF, 3,9-dimethyl-1,2,3,4,5,6-hexahydroazepino[4,5-b]indole (0.3 g, 1.40 mmol) was added and stirred at RT for 5 min. 3-(Oxiran-2-yl)pyridine (254 mg, 1.54 mmol) in DMF (5 mL) was added slowly dropwise and stirred at RT for 14 h. The reaction was monitored by LCMS. After completion of the reaction, the reaction mixture was diluted with water, extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate, evaporated under reduced pressure and purified by reverse phase chromatography to afford 200 mg of 2-(3,9-dimethyl-2,3,4,5-tetrahydroazepino[4,5-b]indol-6(1H)-yl)-1-(pyridin-3-yl)ethanol as the TFA salt.
