Lenvatinib is prepared by condensation of 4-chloro-7-methoxyquinoline-6-carbonitrile (I) with 3-chloro-4-nitrophenol (II) in hot 2,6-lutidine to afford the 4-aryloxy quinoline (III), which by reduction of its nitro group by means of iron and ammonium chloride yields aniline (IV). Aniline (IV) is then condensed with cyclopropyl isocyanate (V), producing urea (VI), which is finally submitted to partial hydrolysis of the nitrile group under basic conditions .
