Procedure

This compound is prepared according to synthesis 43, from 60 mg (0.20 mmol) of 8-amino-4-oxo-4,5-dihydro-3H-pyrrolo[2,3-c]quinoline-1-ethyl carboxylate hydrochloride (synthesis 64) and 31 mg (0.21 mmol) of 3-toluenesulfonyl chloride. After recrystallization from methanol, 33 mg (40%) of 4-oxo-8-(3-toluenesulfonylamino)-4,5-dihydro-3H-pyrrolo[2,3-c]quinoline-1-ethyl carboxylate is obtained in the form of a beige solid.
