合成路线1
该中间体在本合成路线中的序号：(III)Intermediate (III) was prepared by condensation of epoxide (I) with piperazine (II). After removal of the carbobenzoxy protecting group of (III) by catalytic hydrogenation, the resulting amine (IV) was coupled to the valine derivative (V) using EDC to afford amide (VI). Subsequent cleavage of the Boc protecting group of (VI) under acidic conditions gave (VII), which was finally alkylated with the benzodioxolylmethyl halide (VIII) to provide the target compound.
