Tetrahydrofuran → HCID 67774107, compound

Participants

Reaction Steps

Tetrabutylammonium fluoride (1M THF solution, 0.35 mL) was added to a mixture of methyl 1-[3,5-difluoro-4-(trimethylsilyl)pyridin-2-yl]-4-fluoroisoquinoline-7-carboxylate and THF (1.8 mL), and stirred at room temperature overnight. The reaction mixture was diluted with water, and extracted with ethyl acetate. The organic layer was washed with saturated brine, dried, and concentrated under reduced pressure. The resulting residue was purified under silica gel column chromatography (hexane/ethyl acetate) to obtain methyl 1-(3,5-difluoropyridin-2-yl)-4-fluoroisoquinoline-7-carboxylate (55 mg).
