The condensation between cyclohexanone (I) and dimethyl itaconate (II) in the presence of NaOMe in cold Et2O afforded the spirobutenolide (III) together with some hydrolyzed product (IV). A further hydrolytic treatment with aqueous NaOH provided acid (IV), which was then converted to acid chloride (V) by treatment with PCl5 in refluxing cyclohexane. Reaction of this acid chloride with N-(2-methoxyphenyl)piperazine in CH2Cl2 at 0 C produced the title amide.
