合成路线1
该中间体在本合成路线中的序号：(XVIII)Intermediate (XVII) by a treatment with Zn and HOAc eliminates the Troc protecting group, giving the primary amine (XVIII). This compound by treatment with 4-formyl-1-methylpyridinium iodide (NMPC), DBU and oxalic acid in order to convert the nitrile group into an alcohol, provides compund (XIX), which is finally cyclized with 2-(3-hydroxy-4-methoxyphenyl)ethylamine (XX) by means of SiO2 / EtOH, followed treatment with and AgNO3 in acetonitrile/water.
