Dimethylformamide → 6-(4-Bromo-3-(1,3-dioxolan-2-yl)-2-fluorophenoxy)-2-methoxynicotinonitrile

Participants

Reaction Steps

A solution of 6-chloro-2-methoxynicotinonitrile (1.16 g, 6.88 mmol), 4-bromo-3-(1,3-dioxolan-2-yl)-2-fluorophenol (1.81 g, 6.88 mmol), potassium carbonate (1.14 g, 8.26 mmol), and N,N-dimethylformamide (35 mL) was stirred at 80° C. overnight. Water was added and the solution was extracted with ethyl acetate. The organic layer was washed with brine, dried over anhydrous sodium sulfate, and filtered. The solvent was removed under reduced pressure and the residue was purified by silica gel column using Combiflash to give 6-(4-bromo-3-(1,3-dioxolan-2-yl)-2-fluorophenoxy)-2-methoxynicotinonitrile (2.31 g, 85% yield).
