How is 2-(2-Nitrophenyl)ethanamine hydrochloride (CAS: 861337-74-8) typically synthesized?

2-(2-Nitrophenyl)ethanamine hydrochloride is synthesized through a multi-step process involving the reaction of 2-nitrophenylamine with hydrochloric acid. The key steps include the formation of the amine from the nitro group, followed by the protonation of the amine to form the hydrochloride salt. This reaction is typically carried out in an aqueous medium, with careful control of pH and temperature to ensure selectivity.
