Procedure

A mixture of 3-(8-chloro-1,2,3,4-tetrahydro-2-methylpyrido[4,3-b]indol-5-yl)propanoic acid (100 mg, 0.34 mmol), morpholine (29 mg, 0.34 mmol), DCC (77 mg, 0.37 mmol), and DMAP (46 mg, 0.37 mmol) in dry DCM (2.5 mL) was stirred at room temperature for 3 h. The reaction mixture was filtered through Celite and concentrated by rota vapor to obtain 10 mg of 3-(8-chloro-1,2,3,4-tetrahydro-2-methylpyrido[4,3-b]indol-5-yl)-1-morpholinopropan-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).
