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.
