An autoclave (capacity: 500 ml) was charged with 200 parts of methanol and 94.5 parts of triethylamine. After heating the mixture to 130° C., 135 parts of 2-[2-(2-chloro-ethoxy)ethoxy]ethanol was added over a period of 1 hour and the resulting mixture was heated at 130° C. for an additional 4 hours. Crystallization was performed as in Preparation 1 to obtain 205.0 parts of triethyl 2-[2-(2-hydroxy-ethoxy)ethoxy]ethylammonium chloride (yield: 95%).
