该中间体在本合成路线中的序号：(XVIII)Sulfonation of methyl naphthylacetate (XIV) gave sulfonate (XV), which was nitrated at -20 C to produce (XVI) as the major isomer. Reduction of the nitro group of (XVI) employing iron and H2SO4 yielded aminosulfonate (XVII), which was cyclized by means of POCl3 to give sultam (XVIII). The ester group of (XVIII) was finally reduced to alcohol (VII) with LiAlH4.
