Abstract

The present invention provides a method for preparing azoxystrobin intermediates, comprising reacting compound A and dichloropyrimidine in the presence of a trimethylamine catalyst with the addition of a sodium methoxide solution in methanol or the addition of sodium methoxide and methanol separately to produce a mixture of compound B and compound C. Azoxystrobin intermediate compound B and compound C are synthesized from compound A in the present invention, which is catalyzed by using a trimethylamine catalyst, allowing the reaction to have high efficiency and high yield. In addition, the trimethylamine catalyst has a low boiling point and thus can be easily recycled so that the ammoniacal nitrogen content in wastewater can be reduced, and the difficulties and high costs for wastewater processing can be also reduced. The recycled trimethylamine catalyst can be reused in preparing intermediate compound B, which also has a high catalytic effect and can also achieve a high product yield. The method of the present invention has significant synthetical cost advantages and is suitable for industrial production.
