Versuchsvorschrift

5-Bromo-1-chloro-6-hydroxyisoquinoline (108 mg, 0.42 mmol) was mixed with hydrochloric acid (5M, 2 ml) and heated under microwave conditions at 150° C. for 40 minutes. The cooled residue was mixed with methanol and azeotroped to dryness under reduced pressure to give 5-bromo-6-hydroxy-2H-isoquinolin-1-one El-MS: m/z=240 and 242[M+H]+.
