Versuchsvorschrift

3-Dimethylcarbamoyloxypyridine (4.98 g) and chloromethylbenzoate (5.13 g) were heated to 70° C. with stirring for 4 hrs. The hot reaction mixture was poured into 100 ml of diethyl ether with vigorous stirring. The precipitated solids were filtered off and washed twice with anhydrous diethyl ether (100 ml×2). Recrystallization from acetone gave 8.6 g of 3-(dimethylcarbamoyloxy)-1-(phenylcarbonyloxymethyl)pyridinium chloride as prisms, m.p. 175°-176° C.
