Procedure

1.86 parts of 3-thiolacetoxy-dihydrothiophene-4-carboxylic acid methyl ester are reacted with 1.76 parts by volume of sulfuryl chloride in 25 parts by volume of chloroform in the course of one hour at 0° C. The end product is isolated from the reaction mixture by the method described in Example 1c. 1.4 parts (75% of theory) of 3-thiolacetoxy-thiophene-4-carboxylic acid methyl ester of melting point 92°-95° C. are obtained.
