A process for preparing 5,5-disubstituted 4,5-dihydroisoxazole-3-thiocarboxamidine salts of the formula (I), wherein
3-unsubstituted 4,5-dihydroisoxazoles are first reacted with a chlorinating or brominating reagent to give 3-halogenated 4,5-dihydroisoxazoles and the latter then react with thiourea to give the compounds of the formula (I).
一种制备式(I)的5,5-二取代4,5-二氢异噁唑-3-硫代甲酰胺盐的方法,其中首先将未取代的4,5-二氢异噁唑与氯化或溴化试剂反应,得到3-卤代的4,5-二氢异噁唑,然后再将其与硫脲反应得到式(I)化合物。
