反応手順

34 mg (1.5 mmol) of N-phenylthiourea is added to a suspension of 57 mg (0.15 mmol) of 8-(2-bromo-acetyl)-4-oxo-4,5-dihydro-3H-pyrrolo[2,3-c]quinoline-1-ethyl carboxylate in 3 mL of ethanol. The mixture is stirred at 90° C. for 48 hours then the mixture is cooled to room temperature. Triethylamine (2 mmol) is added, then the solvent is evaporated and the product is purified by chromatography on silica (chloroform/methanol/triethylamine 8/2/1). After drying, 11 mg (17%) of 4-oxo-8-(2-phenylamino-thiazol-4-yl)-4,5-dihydro-3H-pyrrolo[2,3-c]quinoline-1-ethyl carboxylate is obtained in the form of a beige solid.
