The reaction of phthalide (I) with pyridine-4-carbaldehyde (II) by means of NaOMe in methanol gives the nonisolated intermediate (III), which rearranges in the reaction medium to yield indenone (IV). The reaction of (IV) with hydrazine hydrate affords the phthalazinone (V), which was activated as the imidoyl chloride (VI) by means of POCl3 and then reacted with 3-chloro-5-trifluoromethylaniline (VII) in ethanol to afford the 1-anilino-phthalazine.
