合成路线2
该中间体在本合成路线中的序号:(III)The title compound was prepared by two related procedures. Treatment of cis-4,5-dimethyl-2-pyrrolidinone (I) with dimethyl sulfate gave the methoxypyrroline (II). The methoxy group of (II) was then displaced with dicyclopropylmethylamine (III) to provide the desired aminopyrroline.

合成路线3
该中间体在本合成路线中的序号:(III)In a more convenient method, pyrrolidinone (I) was converted to the thiolactam (IV) upon treatment with Lawesson's reagent. Alkylation of (IV) with iodomethane furnished the corresponding (S)-methyl derivative (V). This was finally condensed with dicyclopropylmethylamine (III), yielding the title compound.
