How is N-(4-Formylphenyl)methanesulfonamide (CAS: 83922-54-7) typically synthesized?

N-(4-Formylphenyl)methanesulfonamide is typically synthesized via a multi-step process involving the formation of an intermediate methanesulfonamide followed by alkylation of a phenol to form the formylated product. Commonly, this involves the use of sodium methanesulfonate and formylated phenol in the presence of a base like sodium hydroxide, followed by acidification to yield the desired compound.
