5-[2-(Benzenesulfonyl)ethyl]-1H-indole is a chemical compound that contains a nitro group, which is a functional group consisting of a nitrogen atom double-bonded to an oxygen atom. It has been shown to be useful for the synthesis of acetylpyridine derivatives. The synthesis of this compound involves the reaction of indole with 2-chloroethanol and benzenesulfonyl chloride in the presence of sodium hydroxide. This product can also be prepared by reacting chlorination with an alkylamine and nitric acid. 5-[2-(Benzenesulfonyl)ethyl]-1H-indole can be used as a precursor for intermediates in the synthesis of sulphones and salifying agents that are used for polymerization reactions.
