one member being selected from the group consisting
of lower alkyl, halogenated alkyl, lower alkoxy,
lower alkylthio or alkanesulfonyl; R6 is hydrogen or
C1-4-alkyl; and
R7 is an aromatic radical, a heteroaromatic radical, an
aromatic radical substituted with at least one member
selected from the group consisting of lower alkyl,
halogenated alkyl, lower alkoxy, lower alkylthio and
alkanesulfonyl, or (p-) fluorophenyl, or a
heteroaromatic radical substituted with at least one
member being selected from the group consisting of
