Participants

Reaction Steps

A solution of 2-azaspiro-[5.5]-undeca-1,7-diene (14.9 g.; 0.10 mole) is dissolved in dry benzene (150 ml.) and methyl iodide (21.3 g.; 0.15 mole) is added. The mixture becomes warm and a solid separates. The precipitate is filtered, washed with ether and air-dried to afford 27.0 g. (93% yield) of 2-methyl-2-azoniaspiro-[5.5]-undeca-1,7-diene iodide, m.p. 193°-194° C.
