Article abstract of DOI:10.1007/BF00506674

4,6-Dihydroxy-5-acetylpyrimidine was obtained by the solvolysis of 4,6-dialkoxy-5-acetylpyrimidines.The hydrolysis of 4,6-dichloro-5-acetylpyrimidine leads to opening of the heteroring to give s-cis,trans conformers of 2-cyano-3-hydroxy-2-buteneamide. 2',
