Dicyclohexylcarbodiimide → 3-(8-Chloro-1,2,3, 4-tetrahydro-2-methylpyrido[4,3-b]indol-5-yl)-1-(4-methylpiperidin-1-yl)propan-1-one

Participants

Reaction Steps

A mixture of 3-(8-chloro-1,2,3,4-tetrahydro-2-methylpyrido[4,3-b]indol-5-yl)propanoic acid (50 mg, 0.17 mmol), 4-methyl Piperidine (0.02 mL, 0.17 mmol), DCC (38 mg, 0.18 mmol), and DMAP (23 mg, 0.18 mmol) in dry DCM (2 mL) was stirred at room temperature for 3 h. The reaction mixture was filtered through Celite and concentrated to obtain 12 mg of 3-(8-chloro-1,2,3,4-tetrahydro-2-methylpyrido[4,3-b]indol-5-yl)-1-(4-methylpiperidin-1-yl)propan-1-one 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).
