Methyl 6-methylnicotinate (XII) was condensed with 4-pyridinecarboxaldehyde (XIII) in AcOH-Ac2O at 120 C to produce (XIV). Then, ester group was reduced with LiAlH4 to alcohol (XV), and this was subsequently oxidized with DMSO and SO3-pyridine complex to give aldehyde (XVI). Wittig reaction with phosphorane (XVII) afforded ester (XVIII), which was saponified to yield acid (XIX). Finally, coupling of acid (XIX) with amine (XI) in the presence of EDC and HOBt provided the title amide.
