Versuchsvorschrift

Thus, for example, 2-amino-4-phenoxysulfonyl-butyranilide can be obtained by reacting 3-nitro-4-chloro-benzene-sulfonic acid-chloride with phenol to yield 2-nitro-4-phenoxysulfonylchloro-benzene, reacting this product with ammonia to give 2-nitro-4-phenoxy-sulfonyl-aniline, acylating this compound with butyryl-chloride to form 2-nitro-4-phenoxysulfonyl-butyranilide, and by subsequently hydrogenating said product catalytically.
