Treatment of anacardic acid (I) with diethyl sulfate produces the dialkylated derivative (II). Ester group reduction in (II) employing LiAlH4 then yields the benzylic alcohol (III), which is further oxidized to aldehyde (IV) with pyridinium chlorochromate. Condensation of aldehyde (IV) with ethyl acetoacetate (V) in the presence of piperidine and AcOH gives the benzylidene acetoacetate (VI). This is finally condensed with enamino ester (VII) under modified Hantzsh conditions to furnish the target dihydropyridine compound.
