Versuchsvorschrift
In place of the 2-acetylamino-3-ethoxycarbonyl-4-phenylthiophene used in Example 4 there is used an equivalent amount of 2-acetylamino-3-phenylsulphonylthiophene (which was obtained by condensing phenylsulphonylacetonitrile with 2:5-dihydroxy-1:4-dithiane in ethanol containing piperidine and subsequently acetylating) whereby 2-amino-3-phenylsulphonyl-5-nitrothiophene (m.pt 155° - 157° C) is obtained.
