N-(2-Methoxyphenyl)piperazine (I) was alkylated with 4-bromobutyronitrile (II) to provide the 3-cyanopropylpiperazine (III). Subsequent reduction of the cyano group of (III) using LiAlH4 produced the primary amine (IV). The title amide was then obtained by condensation of (IV) with 2-naphthoic acid (V) after activation as the corresponding acid chloride with (COCl)2 or as the mixed anhydride with isobutyl chloroformate.
