合成路线1
该中间体在本合成路线中的序号:(III)condensation of 2-(allyloxymethyl)-1-(2-chloroethoxy)-4-nitrobenzene (VI) with pyrrolidine (XI) in dimethylacetamide at 60 °c affords 1-[2-[2-(allyloxymethyl)-4-nitrophenoxy]ethyl]pyrrolidine (XII), which by reduction with SnCl2 in MeoH/cH2cl2 or with Fe and NH4Cl provides the corresponding aniline (XIII). coupling of amine (XIII) with 4-[3-(allyloxymethyl)phenyl]-2-chloropyrimidine (VIII) In the presence of HCl in BuOH at 100 °c gives the diallyl derivative (XIV), which finally undergoes ring-closing metathesIs In the presence of Grubbs’ second-generation catalyst and TFA in CH2Cl2 at 50 °c or in the presence of the Zhan-1B catalyst .
