合成路线1

The reductive alkylation of tropinone (I) with aniline (II) using either NaBH4 or NaBH(OAc)3 as the reducing agent furnished the endo-isomer (III). Arylation of amine (III) with t-butyl 4-bromobenzoate (IV) produced the (diarylamino)tropane (V). Acid cleavage of the tert-butyl ester of (V) gave acid (VI), which was further coupled to diethylamine, yielding amide (VII). Demethylation of tropane (VII) with 1-chloroethyl chloroformate, followed by methanolysis of the resulting carbamate (VIII), provided the secondary amine (IX). This was finally subjected to reductive alkylation with 3,4-methylenedioxybenzaldehyde (X) to give the title compound.
