Procedure

A solution of 2,3,4,5-Tetrahydro-2-methyl-1H-pyrido[4,3-b]indole (186 mg, 1 mmol), 5-(chloromethyl)-2-methylpyridine (324 mg, 2.3 mmol) and 60% NaH (120 mg, 3 mmol) in DMF (3 ml) were heated at 120° C. for 16 h to obtain 30 mg of 2,3,4,5-tetrahydro-2-methyl-5-((6-methylpyridin-3-yl)methyl)-1H-pyrido[4,3-b]indole after purification by silica gel chromatography (230-400 mesh) using methanol-dichloromethane gradient.
