To an ice cold and stirred mixture of N-(2-hydroxyethyl)dithiocarbamic acid methyl ester (1.513 g) and ethoxyethylene (1.92 ml) is added toluene-p-sulfonic acid monohydrate (9.5 mg). After stirring for 30 minutes at room temperature, the homogeneous solution is mixed with triethylamine (8 μl) and concentrated under reduced pressure to yield N-[2-(1-ethoxyethoxy)ethyl]dithiocarbamic acid methyl ester (2.4 g).
