Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Thionyl Chloride | HCID 24386 | — |
| Reactant | 3-(Aminosulfonyl)-5-nitro-4-phenoxybenzoic acid | HCID 119926 | — |
| Product | 3-Nitro-4-phenoxy-5-sulfamoylbenzoyl chloride | HCID 21506035 | — |
Reaction Steps
A mixture of 3-nitro-4-phenoxy-5-sulphamyl-benzoic acid (5 g) and thionyl chloride (50 ml) was heated on a steam bath for 5 hours. After evaporation in vacuo to dryness, the compound was obtained as a crude product, which was used in the next step without further purification.
