- R.sup.3 is hydrogen or C.sub.1 -C.sub.4 -alkyl,
- R.sup.4 is hydrogen, C.sub.1 -C.sub.4 -alkyl or phenyl,
- R.sup.5 is hydrogen or unsubstituted or substituted C.sub.1 -C.sub.10 -alkyl, unsubstituted or substituted phenyl or allyl and
- X is cyano, nitro, C.sub.1 -C.sub.4 -mono- or dialkylcarbamyl, pyrrolidinocarbonyl, piperidinocarbonyl, morpholinocarbonyl, piperazinocarbonyl, N-(C.sub.1 -C.sub.4 -alkyl)-piperazinocarbonyl, C.sub.1 -C.sub.4 -alkoxycarbonyl, C.sub.1 -C.sub.4 -alkylcarbonyl, unsubstituted or substituted phenylcarbonyl, C.sub.1 -C.sub.4 -alkylsulfonyl or unsubstituted or substituted phenylsulfonyl, and its salts and the rings A and E may furthermore be substituted by methyl, methoxy, chlorine or hydroxy sulfonyl, and its salts.
