Reaction Conditions

Reaction Steps

To a solution of 1-chloro-6-fluoro-4-methoxyisoquinoline (115 mg, 0.543 mmol) in DMSO (5 mL), was added CsF (165 mg, 1.087 mmol) and the reaction was heated to 140° C. for 2 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 the crude product which was purified by silica gel chromatography using 20-40% DCM in hexanes. The product fractions were collected and the solvent was removed under vacuum to give 1,6-difluoro-4-methoxyisoquinoline (71 mg, 67% yield). MS m/z 196.1 (M++1).
