    Synthesis of Alkyl 1-Aryl-1,4-Dihydro-4-Oxo-6-Methylpyridazine-3-Carboxylates

      Abstract
    • In order to get a convenient method for preparation of pyridazinone carboxylate, 1-aryl-1,4-dihydro-4-oxo-6-methyl pyridazine-3-carboxylic acids have been converted to alkyl esters in good yieds by heating them with dialkyl phosphite at 120～30 ℃ for 4 h.
