Versuchsvorschrift

12.9 g (49.5 mmol) 7-bromo-1-chloro-6-fluoro-isoquinoline (94) were dissolved in 250 ml of acetic acid. After addition of 38.7 g (0.5 mol) of ammonium acetate, the solution is stirred at 100° C. After 3 h, the solvent was removed under reduced pressure and the residue was poured into water. The precipitate is filtered and dried to yield 9.91 g (83%) of the title compound. Rt=1.15 min (Method C). Detected mass: 242.2/244.1 (M+H+).
