Reaction Steps

Preparation of the title compound was carried out according to General Method 5. 2,3,4,5-Tetrahydro-2,8-dimethyl-1H-pyrido[4,3-b]indole (Example 1) (100 mg, 0.5 mmol) and benzyl chloride (0.11 ml, 0.9 mmol) in diisopropylamine (2 mL) were heated at 80° C. for 12 h. The contents were basified with 1N NaOH and extracted with ethyl acetate. The organic layer was dried over sodium sulfate and concentrated. The resulting crude product was purified by silica gel Chromatography (230-400 mesh) using methanol-dichloromethane gradient followed by reverse-phase chromatography (C-18, 500 mm×50 mm, Mobile Phase A=0.05% TFA in water, B=0.05% TFA in acetonitrile, Gradient: 10% B to 80% B in 30 min, injection vol. 5 mL) to obtain 20 mg of 5-benzyl-2,3,4,5-tetrahydro-2,8-dimethyl-1H-pyrido[4,3-b]indole as a trifluoroacetate salt.
