The condensation of indane-1,3-dione (I) with benzaldehyde (II) by means of piperidine in refluxing benzene gives 2-benzylideneindane-1,3-dione (II), which is treated with H2O2 and NaOH in methanol to yield the epoxide (IV). The condensation of (IV) with N-(3,4-dichlorophenyl)maleimide (V) (obtained by condensation of 3,4-dichloroaniline (VI) with maleic anhydride (VII) in diethyl ether) in refluxing benzene affords a mixture of two diastereomeric racemates from which the desired isomer (VIII) is separated by column chromatography (1-3). Finally, (VIII) is reduced with NaBH4 in methanol to provide a diastereomeric mixture from which the title product is separated by chromatography.
