合成路线1
该中间体在本合成路线中的序号：(IV)Condensation of phthalic anhydride (I) with 4-methylpyridine (II) and heating with NH2-NH2 hydrate yields phthalazine (III) which is converted into chloro derivative (IV) by directly heating in presence of POCl3 or alternatively by heating a solution of (IV) in CH3CN with HCl/dioxane and POCl3. Phthalazine (III) is added to a melt formed by 4-chloroaniline (V), P2O5 and Et3N.HCl to afford the desired product. Alternatively the final product is obtained by heating (V) with (IV) in EtOH or 1-butanol.

合成路线2
该中间体在本合成路线中的序号：(VI)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 3,4-bis(trifluoromethyl)aniline (VII) in ethanol to afford the 1-anilino-phthalazine.
