Participants

Reaction Steps

This compound is prepared according to synthesis 25, from 150 mg (0.46 mmol) of 8-chlorosulfonyl-4-oxo-4,5-dihydro-3H-pyrrolo[2,3-c]quinoline-1-carboxylic acid (synthesis 2) and 55 μL (0.55 mmol) of 3,5-difluoro-aniline. After purification by chromatography on silica gel (dichloromethane/methanol 95/5) then trituration in diethyl ether, 3 mg (2%) of 8-(3,5-difluorophenylsulfamoyl)-4-oxo-4,5-dihydro-3H-pyrrolo[2,3-c]quinoline-1-ethyl carboxylate is obtained in the form of a white solid.
