合成路线1
该中间体在本合成路线中的序号：(IV)The reaction of 3-(1-propylpiperidin-3(S)-yl)phenol (I) with trifluoromethanesulfonic anhydride gives the triflate (II), which is treated with triisopropylsilylthiol sodium salt and Pd(PPh3)4 to yield the sill sulfanyl compound (III). The desilylation of (III) with HCl in methanol affords the thiophenol (IV), which is methylated with 13C- and 2H-labeled methyl iodide and TEA in dichloromethane, providing the methylsulfanyl derivative (V). Finally, this compound is oxidized to the target sulfone with MCPBA and trifluoroacetic acid.
