The mixture was stirred at room temperature for 15 h. The mixture was poured over ice and stirred until all of the ice had melted during which time a solid precipitated from solution. The brown solid was collected by filtration, washed with water and dried on the filter pad to provide 1.0 g (60% by 1H-NMR, 21%) of 1,7-dichloro-5-fluoro-isoquinolin-6-ylamine. MS calc. for C9H5Cl2FN2 [M]+: 231.05. Found: 231.68.
