该中间体在本合成路线中的序号：(II)

Alkylation of 1-napthol (I) with 1,2-dibromoethane provides the (naphthyloxy)ethyl bromide (II), which is condensed with p-nitrophenethylamine (III) to afford the secondary amine (IV). After acetylation of amine (IV) to produce acetamide (V), the nitro group of (V) is reduced by means of iron and HCl, yielding aniline (VI). Finally, acylation of the amino group of (VI) with methanesulfonyl chloride furnishes the target sulfonamide.
