A highly effective method for the preparation of 7H-1,2,4-triazolo[3,4-b][1,3,4]thiadiazines was developed on the basis of condensation reaction between aryl(hetaryl) α-bromo ketones and commercially available thiocarbohydrazide, followed by treatment of the obtained 2-hydrazinyl-6H-1,3,4-thiadiazine hydrobromides with ortho esters in the presence of trifluoroacetic acid under mild conditions.
在芳基(杂芳基)α-溴代酮缩合反应的基础上,开发了一种高效的7 H -1,2,4-三唑并[3,4- b ] [1,3,4]噻二嗪的制备方法然后,在温和条件下,在三氟乙酸存在下,用原酸酯处理所得的2-肼基-6 H -1,3,4-噻二嗪氢溴酸盐。
