Summary: | The invention relates to the technical field of synthesis of a heterocyclic compound, and particularly discloses a method for preparing 2,4-diaminopyrimidine oxide. The method includes the steps of: cyclizing 3-oxopropionitrile with guanidine under an oxidizing condition to obtain 2,4-diaminopyrimidine oxide, wherein the 3-oxopropionitrile is obtained by oxidizing 3-hydroxypropionitrile, which is a cheap and easily available pharmaceutical chemical, as a raw material. The method of the present invention is green and mild, realizing the synthesis of Aminexil from a simple, cheap and easily available raw material. |
