How is [4-(benzenesulfonyl)phenyl]methanamine (CAS: 94341-56-7) typically synthesized?

[4-(Benzenesulfonyl)phenyl]methanamine (CAS: 94341-56-7) can be synthesized via the reaction of benzenesulfonyl chloride with aniline in the presence of a base such as triethylamine. The process involves the formation of an intermediate N-sulfonyl aniline, which is then reduced to the amine with a suitable reducing agent like sodium borohydride. The yield is typically around 70-80%, depending on the purity of starting materials and reaction conditions.
