New compounds of the formula (I), ##SPC1## wherein R.sub.1 and R.sub.2 each stand for a saturated or unsaturated, straightchained or branched alkyl group, an aralkyl group, a saturated or unsaturated cycloalkyl group or an aryl group, or R.sub.1 and R.sub.2 together with the adjacent nitrogen atom form a substituted or unsubstituted heterocyclic group which can contain a further oxygen or nitrogen hetero atom, But when R.sub.1 is methyl, R.sub.2 is a group other than methyl, are prepared by reacting a compound of the formula (II), ##SPC2## wherein X stands for halogen, with a secondary amine of the general formula (III), r.sub.1 --nh--r.sub.2. (iii) the new compounds of the general formula (I), as well as their pharmaceutical acceptable acid addition salts or quaternary ammonium salts are active primarily in the induction of liver microsomal enzyme, but they also possess antipyretic activity.
公式(I)的新化合物,其中R.sub.1和R.sub.2分别代表饱和或不饱和的直链或支链烷基,芳基烷基,饱和或不饱和的环烷基或芳基,或者R.sub.1和R.sub.2与相邻的氮原子一起形成一个取代或未取代的杂环基团,该基团可以含有进一步的氧或氮杂原子。但当R.sub.1为甲基时,R.sub.2是非甲基基团,通过将公式(II)的化合物与一般公式(III)的二级胺进行反应制备。其中X代表卤素,r.sub.1 --nh--r.sub.2。通式(I)的新化合物,以及它们的药用可接受的酸盐或季铵盐主要在诱导肝微粒体酶方面具有活性,但它们也具有退热活性。
