Abstract: In this work, the reaction of dehydroacetic acid (1) with aqueous ammoniahas been further studied by means of HPLC. In this reaction lutidone (2), lutidonecarboxylic acid (4) and 2,6-dimethyl-4-aminopyridine (6) have been separated or prepared.DHA-imide (3) (3-iminoethyl-4-hydroxy-6-methyl-2-pyrone) is the intermediate which gives various compounds under different conditions. The mechanism of this reaction is discussed.The structures of compounds have beeen characterized by IR, 1HNMR and MSspectra.
Key words: Dehydroacetic acid, 2,6-dimethyl-4-hydroxypyridine
