Ethanol → HCID 58306959, compound

Participants

Reaction Steps

To 4-{(1S)-1-[({1-[(6-chloropyridin-3-yl)methyl]-1H-indol-7-yl}carbonyl)amino]ethyl}benzoic acid (95 mg) were added ethanol (2.0 mL) and piperidine (65 μL), followed by stirring at room temperature overnight. After concentration under reduced pressure, DMSO (1.0 mL), piperidine (65 μL), and potassium tert-butoxide (61 mg) were added thereto, followed by stirring at 80° C. for 2 hours. To the reaction mixture was added a 10% aqueous citric acid solution (10 mL), followed by extraction with ethyl acetate. The obtained organic layer was washed with water, dried over anhydrous sodium sulfate, filtered, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (chloroform/methanol=99/1-95/5) to obtain 4-{(1S)-1-[({1-[(6-ethoxypyridin-3-yl)methyl]-1H-indol-7-yl}carbonyl)amino]ethyl}benzoic acid (9.0 mg).
