reduction of 2,3-dimethyl-4-(o-nitrophenylthio)-1-phenyl-3-pyrazolin-5-one by sodium borohydride and palladium–charcoal gave the corresponding hydroxylamine. The action of hydrochloric acid on this hydroxylamine gave the p-chloroamine. In a similar manner, treatment of some 2H-1,4-benzothiazine and -benzoxazine hydroxamic acids with hydrochloric acid resulted in the formation of 7-chloro-2H-1,4-benzothiazine
2,3-二甲基-4-(邻硝基苯硫基)-1-苯基-3-吡唑啉-5-酮用硼氢化钠和钯-炭还原得到相应的羟胺。盐酸对该羟胺的作用产生对氯胺。以类似的方式,用盐酸处理一些 2H-1,4-苯并噻嗪和 -苯并恶嗪异羟肟酸导致形成 7-氯-2H-1,4-苯并噻嗪和 -苯并恶嗪内酰胺。
