- Method for synthesizing azaconazole through 4-amino-4H-1,2,4-triazole alkylation
-
The invention discloses a method for synthesizing azaconazole through 4-amino-4H-1,2,4-triazole alkylation. The method comprises step 1, preparing a raw material which is shown in a following image; step 2, synthesizing 1-(2,4-dichlorophenyl)-2-(1H-1,2,4-triazole-1-yl) ethanone; step 3, synthesizing azaconazole. The method disclosed by the invention has the advantages that development of a novel azaconazole bactericide successfully fills the blank in China, synthesis researches of similar derivatives based on the azaconazole bactericide will be in the ascendant, and successful development andindustrial implementation of varieties of novel bactericides have a far-reaching influence on national economy development. The method disclosed by the invention is an azaconazole synthesizing method.
