Synthesis of Pyrrolidine Derivatives with Pharmacological Activity. IX. Synthesis of 1, 1, 5-Trimethyl-2-ethyl-and 1, 1, 2, 4, 5-Pentamethyl-3-diphenylmethylenepyrrolidinium Iodide as Potential Anticholinergic Agents

Abstract
To examine anticholinergic activity of pyrrolidines analogous to 1,1-diethyl-3-diphenylmethylene-2-methylpyrrolidinium Br (Prifinium Br), cis- and trans-1,1,5-trimethyl-2-ethyl- and cis- and trans-1,1,2,4,5-pentamethyl-3-diphenylmethylene-pyrrolidinium iodides were synthesized. Their pharmacological activity was reported.
