ABSTRACT:
The present invention relates to a process for the preparation of compounds of the general formula I ##STR1## by reaction of compounds of the general formula II ##STR2## with amines of the general formula III ##STR3## wherein R.sup.1 and R.sup.2 independently of one another denote hydrogen, (C.sub.1 -C.sub.4)-alkyl, C.sub.1 -C.sub.4)-hydroxyalkyl or (C.sub.5 -C.sub.6)-cycloalkyl, or, together with the nitrogen atom carrying them, form (C.sub.4 -C.sub.6)-heterocyclyl and R.sup.3 and R.sup.4 independently of one another denote hydrogen, (C.sub.1 -C.sub.4)-alkyl, (C.sub.1 -C.sub.4)-hydroxyalkyl, (C.sub.1 -C.sub.2)-alkylcarbonyl or tosyl.
