The azidomethyl oxazolidinone (I) was reduced to the corresponding amine (II) by treatment with triphenylphosphine, followed by aqueous hydrolysis of the intermediate iminophosphorane. Condensation of amine (II) with ethyl dithioacetate (III) produced thioacetamide (IV). After acidic cleavage of the tert-butyl ester, the resultant carboxylic acid (V) was converted to the active ester (VI) upon treatment with pentafluorophenyl trifluoroacetate. Finally, displacement of the pentafluorophenyl ester (VI) with methylamine gave rise to the target N-methyl amide.
