実験手順

87 mg (1.2 mmol) of (2,6-dichlorophenyl)-thiourea is added to a suspension of 124 mg (0.33 mmol) of 8-(2-bromo-acetyl)-4-oxo-4,5-dihydro-3H-pyrrolo[2,3-c]quinoline-1-ethyl carboxylate in 3.5 mL of ethanol. The mixture is stirred at 90° C. for 6 hours then the mixture is cooled to room temperature. The solvent is evaporated, then the product is purified by preparative LCMS. After drying, 43 mg (26%) of 8-[2-(2,6-dichlorophenylamino)-thiazol-4-yl]-4-oxo-4,5-dihydro-3H-pyrrolo[2,3-c]quinoline-1-ethyl carboxylate is obtained in the form of a beige solid.
