Procedure
5.0 g (17 mmol) of the compound of Example 1 were dissolved in a mixture of 200 ml of toluene, 100 ml of ether and 50 ml of methanol. While stirring 50 ml of methyl iodide were added at room temperature. After 24 hrs crystals had formed. The mother liquor was filtered off and the crystals collected. This gave 6.75 g (91%) of the quaternary iodide. m.p. >260° C. (dec.).
