Versuchsvorschrift

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), Isoindoline (23 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 16.3 mg of 2-(1,2,3,4-tetrahydro-2,8-dimethylpyrido[4,3-b]indol-5-yl)-1-(isoindolin-2-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).
