1-Ethyl-3-(3'-dimethylaminopropyl)carbodiimide → HCID 10627406, compound

Participants

Reaction Steps

To a solution of 2-[(E)-3-(6-carboxypyridin-3-yl)acryloylaminomethyl]-1-[2,4-dichloro-3-(2-methylquinolin-8-yloxymethyl)phenyl]pyrrole (60 mg) and methylamine hydrochloride (7.59 mg) in N,N-dimethylformamide (2 ml) were added 1-ethyl-3- (3-dimethylaminopropyl) carbodiimide (19 mg) and 1-hydroxybenzotriazole (20.7 mg) at ambient temperature, and the mixture was allowed to stand for 1 day at the same temperature. The reaction mixture was poured into water and extracted with chloroform. The extract was washed with water and saturated sodium bicarbonate solution, dried over magnesium sulfate and evaporated in vacuo. The residue was purified by preparative thin layer chromatography (chloroform:methanol=10:1, V/V) to give 1-[2,4-dichloro-3-(2-methylquinolin-8-yloxymethyl)phenyl]-2-[(E)-3-[6-(methylcarbamoyl)pyridin-3-yl]acryloylaminomethyl]pyrrole (58 mg) as amorphous powder.
