A series of 2- and 5-(1,1-dimethyl-1,2,5,6-tetrahydropyridinium-3-yl)oxadiazoline iodides, which might be used as M 1 muscarinic receptor agonists, was synthesized from nicotin-aldehyde and nicotinhydrazine, respectively. Their structures were characterized by 1H NMR, IR, MS spectra and elemental analysis.
