Amine (I) was alkylated with 4-nitrophenethyl bromide (II) in refluxing isopropanol to yield the tertiary amine (III). Hydrogenation of the nitro group of (III) employing Pd/C afforded aniline (IV). Subsequent condensation of (IV) with methanesulfonyl chloride in the presence of Et3N produced the corresponding sulfonamide. The title compound was finally isolated as the hydrochloride salt.
