  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 120～130 ℃ for 4 h.

  为探索哒嗪酮羧酸酯的简便合成方法，通过亚磷酸二烷基酯与1-芳基-1,4-二氢-4-氧-6-甲基哒嗪-3-羧酸（摩尔比为2∶1）在120～130 ℃下共热4 h，得到7个收率63%～85%的哒嗪酸烷基酯。
