该中间体在本合成路线中的序号：(III)The alkylation of N-acetyl-L-cysteine (I) with farnesyl bromide (II) in methanolic ammonia provided the corresponding farnesyl thioether (III). After activation of the S-alkylated acid (III) as the mixed anhydride (IV) using isobutyl chloroformate and N-methylmorpholine, reaction with diazomethane yielded the diazomethyl ketone (V). This was then converted into the title chloromethyl ketone by treatment with HCl in ethyl acetate.
