该中间体在本合成路线中的序号：(A)Coupling of methacryloyl chloride (I) with substituted aniline (II) in dimethylacetamide yields amide (III), which is then converted into the epoxy derivative (IV) by oxidation with m-chloroperbenzoic acid (mCPBA) and 4-methyl-2,6-di-tert-butylphenol (A) in refluxing 1,1,1-trichloroethane. Condensation of (IV) with thiol (V) by means of NaH in THF provides fluorophenylthio derivative (VI), which is finally oxidized with mCPBA in CH2Cl2 to furnish the desired compound trichloroethane.
