1.41 g of the sodium salt of 6-pentyl-6-methyl-2-oxo-1,4-oxathiane-3-acetic acid and 0.63 g of 1-bromopropane are boiled for 1 hour in a mixture of 15 ml of dry ethanol and 5 ml of dry diethyl ether. The mixture is further stirred for 1 hour at room temperature. It is permitted to stand for about 12 hours at 0° and filtered. After distilling off the solvent, 6-pentyl-6-methyl-2-oxo-1,4-oxathiane-3-acetic acid n-propyl ester is obtained.
