Participants

Reaction Steps

5 g (16 mmol) Methyl 2-(4,6-dimethoxy-2-pyrimidinyloxy)-2-phenylacetate was dissolved in 50 ml water/ethanol (1:1) and treated with 0.9 g potassium hydroxide. After stirring for 16 hours at room temperature, the mixture was extracted with ethyl acetate. The aqueous phase was acidified with 10% hydrochloric acid until it was pH 2 and extracted with ethyl acetate. After drying over magnesium sulphate, the ethyl acetate phase was concentrated the solid residue recrystallised from diisopropyl ether/ethyl acetate mixture.
