Procedure

To a solution of 1-chloro-7-fluoro-5-methoxyisoquinoline (350 mg, 1.654 mmol) in DMSO (3 mL), was added CsF (502 mg, 3.31 mmol) and the mixture was heated to 140° C. for 4 h. The reaction was diluted with EtOAc and washed with water, and brine. The organic phase was collected, dried over sodium sulfate, and concentrated under vacuum to give 1,7-difluoro-5-methoxyisoquinoline (340 mg, 105% yield) which was not purified further. MS m/z 196.1 (M++1).
