実験手順

To the stirred mixture of 3,5-dichloro-4-{[4-(cyclopropylcarbonyl)-1H-pyrrolo[3,2-c]pyridin-1-yl]carbonyl}benzoic acid (50 mg, 0.119 mmol), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (26.8 mg, 0.14 mmol) and 1-hydroxybenzotriazole (19 mg, 0.14 mmol) in N,N-dimethylformamide, was added tert-butyl(2-aminoethyl)carbamate (19 mg, 0.119 mmol). The reaction mixture was stirred at room temperature for about 16 hours. The reaction mixture was poured drop wise into cold saturated solution of sodium bicarbonate. The precipitated solid was filtered, washed with water and dried. Purification by preparative thin layer chromatography (2% methanol and dichloromethane as eluent) afforded tert-butyl {2-[(3,5-dichloro-4-{[4-(cyclopropylcarbonyl)-1H-pyrrolo[3,2-c]pyridin-1-yl]carbonyl}benzoyl)amino]ethyl}carbamate (23 mg, 35%).
