N-[4-[(2-Chloroethyl)methylamino]-2-butynyl]-5-methyl-2-pyrrolidone (3) and N-[4-[(2-bromoethyl)methylamino]-2-butynyl]-5-methyl-2- pyrrolidone (4) were synthesized. Compounds 3 and 4 cyclized in neutral aqueous solution to an aziridinium ion (4A). The rate constants for the cyclization of 3 and 4 at 37 degrees C were 0.025 and 0.89 min-1, respectively. The aziridinium ion was equipotent with carbachol
