The title compound was prepared by following general procedure 4. 3,9-Dimethyl-1,2,3,4,5,6-hexahydroazepino[4,5-b]indole (214 mg, 1.0 mmol) was taken with copper iodide (19 mg, 0.1 mmol), L-proline (23 mg, 0.2 mmol), potassium phosphate tribasic (426 mg, 2.0 mmol) and (2-bromoethyl)benzene (185 mg, 1 mmol) and DMF was added, the reaction was stirred at 90° C. under argon atmosphere for 12 h. The reaction was monitored by LCMS. After completion of the reaction, water was added and extracted with ethyl acetate. The organic layer was washed with water, dried over sodium sulfate and concentrated under vacuum. The crude so obtained was purified by column chromatography (silica gel 100-200 mesh) (gradient 5% MeOH:DCM). The pure product was converted to oxalate salt using oxalic acid and THF.
