Procedure
Analogously to Example 1, from maleic acid anhydride and 2-hydroxy-3-m-chlorophenoxypropane-1-thiol in the presence of diisopropylamine and the usual working up of the reaction mixture, 6-m-chlorophenoxymethyl-2-oxo-1,4-oxathiane-3-acetic acid is obtained. It is separated into two isomers using chromatographic purification:
