How are sulfa drugs synthesized from benzene

WebAny sulfonamide can be considered as derived from a sulfonic acidby replacing a hydroxylgroup (−OH) with an amine group. In medicine, the term "sulfonamide" is sometimes used as a synonym for sulfa drug, a derivative or variation of sulfanilamide. The first sulfonamide was discovered in Germany in 1932.
