Versuchsvorschrift

Acetyl chloride (100 ml, 36 eq.) was added dropwise to absolute EtOH (780 ml) at 0° C. After stirring the resulting solution for 20 min at r.t., 5-ethoxy-2,6-dihydroxy-pyrimidine-4-carboxylic acid (7.76 g, 1 eq.) was added in one portion and the mixture was refluxed overnight. The volatiles were evaporated in vacuo to give 5-ethoxy-2,6-dihydroxy-pyrimidine-4-carboxylic acid ethyl ester as an off-white solid (8.85 g, 100%).
