In a continuing search for new biologically active agents derived from indolizine, 3-(2-aminoethyl)-2-methylindolizine, 3-(2-aminoethyl)-2-methyl-5,6,7,8-tetrahydroindolizine, and some mono- and di-N-substituted derivatives were prepared. Initial pharmacological screening showed that these compounds possess anti-5-hydroxytryptamine, antihistamine, antiacetylcholine, and CNS-depressant activities.
