The invention relates to compounds of the formula: ##STR1## in which R represents hydrogen or a lower alkyl radical and R.sub.1 and R.sub.2 separately represent hydrogen, a lower alkyl, cycloalkyl or benzyl radical, or represent, together with the nitrogen atom to which they are bonded, a heterocyclic radical such as a morpholino, 4-(pyrimidin-2-yl)-piperazinyl or 4-phenylpiperazinyl the phenyl radical of which being optionally substituted by halogen, lower alkoxy or trifluoromethyl, having CNS activity and particularly hypnotic properties. Moreover the compounds in which R.sub.1 and R.sub.2 are hydrogen can be used in the treatment of heart failure.
本发明涉及式子:##STR1##其中R代表氢或较低的烷基基团,R.sub.1和R.sub.2分别代表氢、较低的烷基、环烷基或苄基基团,或者与它们结合的氮原子一起代表杂环基团,例如吗啡啶基、4-(嘧啶-2-基)-哌嗪基或4-苯基哌嗪基,其中苯基可以选择性地被卤素、较低的烷氧基或三氟甲基取代,具有中枢神经系统活性,尤其是催眠作用。此外,R.sub.1和R.sub.2均为氢的化合物可用于治疗心力衰竭。
