HCID 215060353-Nitro-4-phenoxy-5-sulfamoylbenzoyl chloride

Procedure

A mixture of 3-nitro-4-phenoxy-5-sulphamyl-benzoic acid (5g) 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.
