Reaction Steps

A mixture of 2-(1,2,3,4-tetrahydro-2,8-dimethylpyrido[4,3-b]indol-5-yl)acetic acid (50 mg, 0.205 mmol), 3-methyl piperidine (19 mg, 0.205 mmol), DCC (46 mg, 0.22 mmol), and DMAP (27 mg, 0.22 mmol) in dry DCM (2.0 mL) was stirred at room temperature for 3 h. The reaction mixture was filtered through Celite and concentrated using rotary evaporator afforded 34.2 mg of 2-(1,2,3,4-tetrahydro-2,8-dimethylpyrido[4,3-b]indol-5-yl)-1-(3-methylpiperidin-1-yl)ethanone as TFA Salt after purification 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).
