Reaction Steps

The title compound was prepared by following general procedure 5. To a stirred suspension of sodium hydride (67 mg, 0.28 mmol) in 5 mL of DMF, 3,9-dimethyl-1,2,3,4,5,6-hexahydroazepino[4,5-b]indole (0.2 g, 0.934 mmol) was added and stirred at RT for 5 min. 2-(4-Chlorophenyl)-2-methyloxirane (235 mg, 1.4 mmol) was added slowly dropwise and stirred at RT for 14 h. The reaction was monitored by TLC and LCMS. After completion of the reaction, water was added, extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate, evaporated under reduced pressure and purified by column chromatography using 10% methanol-DCM. The freebase (30 mg, 0.078 mmol) was dissolved in THF (1.0 mL) and oxalic acid (9.8 mg, 0.078 mmol) in THF (1.0 mL) was added slowly, the mixture was stirred at RT for 20 min. and the formed solid was filtered, washed with ether and dried to afford product as oxalate salt.
