Hydrochloric Acid → Ethyl 3-oxo-3-(pyrimidin-4-yl)propanoate

Participants

Reaction Steps

To a 25% solution (5.31 g, 10.52 mmol) of potassium tert-amylate in toluene was added dropwise a solution of ethyl pyrimidine-4-carboxylate (1.00 g, 6.57 mmol) and ethyl acetate (1.09 mL, 11.1 mmol) in toluene (2.4 ml) at room temperature. Disappearance of the ethyl ester was confirmed by HPLC analysis, water (5 mL), ethyl acetate (5 mL) and concentrated hydrochloric acid (0.45 mL) were added, and the mixture was extracted with ethyl acetate (4 mL). The organic layer was dried over sodium sulfate, and the solvent was evaporated under reduced pressure to give ethyl 3-oxo-3-(pyrimidin-4-yl)propionate (0.97 g, 76%).
