This invention relates to indazole derivatives, to processes for their preparation and to pharmaceutical compositions containing them. More specifically this invention relates to 4, 5, 6, 7-tetrahydroindazoles bearing at the 3-position an amino substituent. This invention also relates to processes for producing the same which include the steps of condensing a substituted cyclohexanone with a secondary amine, reacting the thus formed enamine either with an isocyanate or thiocyanate or with phosgene imonium salt and cyclizing the intermediate compound with a hydrazino derivative. The compounds of the invention have therapeutic utility, namely as a means for controlling fertility in mammals.
该发明涉及吲唑衍生物,其制备方法以及含有它们的药物组合物。更具体地,该发明涉及3-位置带有氨基取代基的4,5,6,7-四氢吲唑衍生物。该发明还涉及制备这些化合物的方法,包括将取代的环己酮与二级胺缩合,将形成的烯胺与异氰酸酯或硫氰酸酯或光气亚胺盐反应,以及用肼衍生物使中间化合物环化。该发明的化合物具有治疗用途,即作为控制哺乳动物生育的手段。
