Dimethylformamide → 5-Bromo-2-(2,2-diethoxyethoxy)pyrimidine

Participants

Reaction Steps

2,2-Diethoxyethanol (1.6 g) and cesium carbonate (5.8 g) were added to DMF solution (10 mL) of 5-bromo-2-chloropyrimidine (1.15 g), and stirred at room temperature for 12 hours. After addition of water, the reaction liquid was extracted with ethyl acetate and dried over anhydrous magnesium sulfate. Concentrating the solvent under reduced pressure, the residue was purified on silica gel column chromatography (C-200; ethyl acetate:hexane=1:9-1:4) to provide the title compound (1.63 g, 94%).
