The present invention relates to new pharmacologically valuable, basically substituted heterocyclic compounds of the formula ##EQU1## wherein X represents --N=N-- --ch=n-- ##EQU2## R represents an aliphatic, cycloaliphatic, araliphatic or aromatic amine radical having 2 to 10 carbon atoms or the radical of a 5, 6 or 7 ring-membered heterocyclic amine optionally containing an additional N, O or S hetero atom, the radical being attached through the nitrogen atom, R.sub.1 and R.sub.2 represent alkoxy groups containing 1 - 4 C-atoms, R.sub.3 represents lower alkyl having 1 - 3 C-atoms and m and n are 1, 2 or 3. The above derivatives are produced by acylating heterocyclic derivatives having the formula ##STR1## with an alkoxycinnamic acid of the general formula ##STR2## OR A FUNCTIONAL DERIVATIVE OF THE LATTER, OPTIONALLY IN THE PRESENCE OF AN ACID-BINDING AGENT, THE RADICALS R, R.sub.1, R.sub.2, n and m having the meanings set out above.
本发明涉及一种新的具有药理学价值的、基本上取代的杂环化合物,其化学式为##EQU1##其中X表示--N=N-- --ch=n-- ##EQU2##R表示具有2至10个碳原子的脂肪族、环脂族、芳基脂肪族或芳香族胺基基团,或者是含有一个额外的N、O或S杂原子的5、6或7个环成员的杂环胺基团,该基团通过氮原子连接,R.sub.1和R.sub.2表示含有1-4个碳原子的烷氧基,R.sub.3表示具有1-3个碳原子的低级烷基,m和n分别为1、2或3。上述衍生物是通过用一般式##STR2##或其功能衍生物酰化具有式##STR1##的杂环衍生物制备而成的,其中,可选地在存在酸结合剂的情况下,基团R、R.sub.1、R.sub.2、n和m具有上述含义。
