Procedure

4-{[7-(Acetylamino)-1H-pyrrolo[2,3-c]pyridin-3-yl]carbonyl}-3,5-dichlorobenzoic acid (0.1 g, 0.25 mmol) was taken in a reaction vial. To it 2-(2-aminoethoxyl)ethanol (0.029 g, 2.8 mmol), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (0.073 g, 3.8 mmol), 1-hydroxybenzotriazole (0.051 g, 3.8 mmol) and dimethylformamide (2 mL) were added. The whole reaction mixture was stirred at room temperature for overnight. Water (20 mL) was added to the reaction mixture, extracted with ethyl acetate (3×50 mL). The organic layer was dried over anhydrous sodium sulfate and concentrated under vacuum to get the crude mass which was purified by flash column chromatography to get 4-{[7-(acetylamino)-1H-pyrrolo[2,3-c]pyridin-3-yl]carbonyl}-3,5-dichloro-N-[2-(2-hydroxyethoxyl)ethyl]benzamide (0.035 g, 29%).
