3-aminopyrroles, methods for their synthesis and for their pharmaceutical use

A 3-aminopyrrole of Formula (I) ##STR17## wherein R.sup.1 is H, or a methyl, ethyl, or benzyl residue,

• R.sup.2 is H, or a formyl, acetyl, methoxycabonyl, or ethoxycarbonyl residue,
• R.sup.3 is H, or a methyl, or phenyl residue,
• R.sup.4 is a methyl or phenyl residue, or R.sup.3 and R.sup.4 are taken together with the nitrogen from a morpholino, pyrrolidino or piperidino residue,
• R.sup.5 is a phenyl, p-toluyl, p-ethylphenyl, m-anisyl, p-anisyl, 4-fluorophenyl, 4-chlorophenyl, 3-bromophenyl, 4-bromophenyl, 3,4-dimethoxyphenyl or 4-biphenyl residue, and
• R.sup.6 is H, or R.sup.5 and R.sup.6 taken together are a tetramethylene residue, or a pharmaceutically acceptable salt thereof,
• with the proviso that if R.sup.1 and R.sup.6 are respectively hydrogen and NR.sup.3 R.sup.4 morpholino then R.sup.2 and R.sup.5 respectively are not methoxycarbonyl and phenyl, ethoxycarbonyl and phenyl, methoxycarbonyl and p-chlorophenyl, methoxycarbonyl and p-toyl, ethoxycarbonyl and p-tolyl, or methoxycarbonyl and p-anisyl.
