Reaction Steps

3-Dimethylcarbamoyloxypyridine (1.66 g) and chloromethylcyclopropanecarboxylate (2.70 g) were heated to 90° C. with stirring for 3 hrs. The reaction mixture was treated in a similar manner as described in Example 1 to give 2.77 g of 3-(dimethylcarbamoyloxy)-1-(cyclopropylcarbonyloxymethyl)pyridinium chloride as oil. The structure was determined by N.M.R.
