carbonitrile with methylmagnesium iodide and ethylmagnesium bromide afforded the corresponding alkyl (4,5-dichloroisothiazol-3-yl) ketones. The reaction of (4,5-dichloroisothiazol-3-yl) methyl ketone with morpholine and piperidine provided 5-morpholino-(piperidino)-substituted derivatives, by the action of sodium borohydride in 2-propanol the keto group was reduced to alcoholic hydroxy group. The bromination
4,5-二氯异噻唑-3-基腈与甲基碘化镁和乙基溴化镁反应,得到相应的烷基(4,5-二氯异噻唑-3-基)酮。(4,5-二氯异噻唑-3-基)甲基酮与吗啉和哌啶的反应提供了5-吗啉代-(哌啶子基)取代的衍生物,通过硼氢化钠在2-丙醇中的作用,酮基还原为醇羟基团体。(4,5-二氯异噻唑-3-基)甲基酮与元素溴的溴化反应生成溴甲基(4,5-二氯异噻唑-3-基)酮,其与硫脲反应生成2-氨基-4-(4,5 -二氯异噻唑-3-基)噻唑。
