Paragraph 0015; 0018; 0021; 0024, (2017/04/29)
The invention provides a preparation method for irsogladine maleate, and belongs to the technical field of medicinal and chemical synthesis. The method comprises the following steps: carrying out a condensation reaction between 2,5-dichlorobenzonitrile and dicyandiamide in a non-protic strong polarity solvent with the existence of a basic catalyst to obtain an intermediate II, and enabling the intermediate II and maleic acid to salify in glyceroformol; re-crystallizing a salt in an acetic acid-acetone mixed solution to obtain the irsogladine maleate. The preparation method is easy to operate, high in yield and high in purity, can effectively shorten reaction time, and has a good industrial application value.
