Versuchsvorschrift

In sulfuric acid (30 ml) was dissolved 3.323 g of 1-chloro-6-(4-toluenesulfonylamino)isoquinoline (Preparation Example 22), followed by stirring at room temperature overnight. The reaction mixture was poured onto ice, and basified by adding an aqueous sodium hydroxide and then potassium carbonate, followed by extracting with ethyl acetate. The extract was washed with brine, dried over anhydrous magnesium sulfate and the solvent was evaporated, to give the title compound (1.37 g, 76.81%) as yellowish brown crystals.
