Reaktionsschritte

3-Dimethylcarbamoyloxypyridine (1.66 g) and chloromethylhexanoate (2.0 g) were heated to 90° C. with stirring for 3 hours. The reaction mixture was treated in a similar manner as described in Example 1 to give 2.65 g of 3-(dimethylcarbamoyloxy)-1-(hexanoyloxymethyl)-pyridinium chloride as colorless powdery crystals. It was impossible to precisely measure the melting point because of high hygroscopicity. The structure was determined by N.M.R.
