A process for preparing a 4-amino-1,2,4-(4H)triazole derivative compositions having the formula ##STR1## wherein R is hydrogen or an alkyl group containing from 1 to about 10 carbon atoms, which alkyl group can be additionally substituted by one or more aryl, heteroaryl, hydroxy, or alkenyl substituents, comprising the step of reacting hydrazine or an aqueous hydrazine solution with a carboxylic acid having the formula RCO.sub.2 H in the presence of an insoluble polymer containing acidic functional groups sufficiently strong to cause the reaction to proceed under mild conditions to produce a product of high yield and purity.
一种制备4-氨基-1,2,4-(4H)三唑衍生物组合物的方法,其化学式为##STR1##其中R为氢或含有1至约10个碳原子的烷基基团,该烷基基团可以额外被一个或多个芳基、杂环芳基、羟基或烯基取代,包括在存在足够强的含有酸性功能基团的不溶性聚合物的条件下,通过将叠氮或水合叠氮溶液与具有化学式RCO.sub.2 H的羧酸在温和条件下反应,以产生高收率和纯度的产物。
