Aminomethyl heterocyclic compounds

An aminomethylheterocyclic compound of the formula ##STR297## in which X represents oxygen or sulphur,

• R represents hydrogen, or represents straight-chain or branched alkyl with 1 to 6 carbon atoms, or represents phenyl or cyclohexyl, in each case unsubstituted or mono-, di- or tri-substituted by identical or different substituents selected from the group consisting of alkyl with 1 to 4 carbon atoms or halogen, and
• R.sup.1 and R.sup.2 independently of one another each represent hydrogen;
• or represent in each case straight-chain or branched alkyl with 1 to 12 carbon atoms, alkenyl with 3 to 8 carbon atoms, alkinyl with 3 to 8 carbon atoms, hydroxyalkyl with 2 to 6 carbon atoms, alkoxyalkyl or dial-koxyalkyl with in each case 1 to 6 carbon atoms or hydroxyalkoxyalkyl with 2 to 6 carbon atoms in the individual alkyl parts, alkoxycarbonyl alkyl with 1 to 6 carbon atoms in the alkoxy and alkyl part, or represent in each case straight-chain or branched dioxolanylalkyl, dioxanylalkyl or oxolanylalkyl with in each case 1 to 4 carbon atoms in the alkyl part, or represent cycloalkyl or cycloalkylalkyl with in each case 3 to 7 carbon atoms in the cycloalkyl part and where appropriate 1 to 4 carbon atoms in the straight-chain or branched alkyl part and in each case unsubstituted or mono- or poly-substituted in the cycloalkyl part by identical or different substituents selected from the group consisting of halogen and in each case straight-chain or branched alkyl, alkoxy, halogenoalkyl and halogenoalkoxy with in each case 1 to 4 carbon atoms and where appropriate 1 to 9 identical or different halogen atoms;
• or furthermore represent arylalkyl, arylalkenyl or aryl with in each case 6 to 10 carbon atoms in the aryl part and where appropriate up to 6 carbon atoms in the straight-chain or branched alkyl or alkenyl part, in each case unsubstituted or mono- or poly-substituted in the aryl part by identical or different substituents selected from the group consisting of halogen, cyano, nitro and in each case straight-chain or branched alkyl, alkoxy, alkylthio, halogenoalkyl, halogenoalkoxy, halogenoalkylthio, alkoxycarbonyl and alkoximinoalkyl with in each case 1 to 4 carbon atoms in the individual alkyl parts and where appropriate 1 to 9 identical or different halogen atoms, or
• R.sup.1 and R.sup.2, together with the nitrogen atom to which they are bonded, represent a heterocyclic radical of the formula ##STR298## which is unsubstituted or mono- or polysubstituted by identical or different substituents selected from the group consisting of straight-chain or branched alkyl and hydroxyalkyl with in each case 1 to 4 carbon atoms, or an acid addition salt thereof.
