Procedure

The title compound was prepared according to General Method 3. 2,3,4,5-Tetrahydro-2,8-dimethyl-1H-pyrido[4,3-b]indole (See Example 1) (400 mg, 2 mmol), 2-vinylpyridine (500 mg, 5 mmol), sodium (30 mg, 1.3 g atom), and CuSO4 (20 mg, catalytic) were heated in EtOH (8 mL) at 150° C. overnight (16 h). The contents were evaporated to dryness under vacuo. Water was added and the contents were extracted with ethyl acetate, dried over anhydrous sodium sulfate, and concentrated. The resulting crude product was purified 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 15 mg of 2,3,4,5-tetrahydro-2,8-dimethyl-5-(2-(pyridin-2-yl)ethyl)-1H-pyrido[4,3-b]indole as a trifluoroacetate salt.
