|---|---|---|---|
| Reactant | Phenol | HCID 996 | — |
| Reactant | Benzenesulfonyl chloride, 4-chloro-3-nitro- | HCID 7323 | — |
| Reactant | 2-Amino-4-phenoxysulfonyl-butyranilide | HCID 20385152 | — |
| Product | Phenyl 4-chloro-3-nitrobenzenesulfonate | HCID 266121 | — |
Reaction Steps
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.
