Reaction Steps

To a solution of 1-chloro-7-fluoro-3-(4-isopropoxyphenyl)-6-methoxyisoquinoline (1 g, 2.89 mmol) in DMSO (6 mL), was added CsF (0.879 g, 5.78 mmol) and the mixture was heated to 140° C. for 4 hrs. The reaction was diluted with Ethylacteate 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 50% DCM/Hexanes. The product fractions were collected and the solvent removed under vacuum to give 1,7-difluoro-3-(4-isopropoxyphenyl)-6-methoxyisoquinoline (750 mg, 79% yield). MS: MS m/z 330.1 (M++1).
