Versuchsvorschrift
1.59 parts of 3-methoxy-dihydrothiophene-4-carboxylic acid amide are reacted with 0.88 part by volume of sulfuryl chloride in 25 parts by volume of carbon tetrachloride in the course of 2 hours at 0° C. The end product is isolated from the reaction mixture by the method described in Example 1c. 1.17 parts (75% of theory) of 3-methoxythiophene-4-carboxylic acid amide are obtained.
