0.5 g (1.29 mmol) of N-{[(5S)-3-(4-aminophenyl)-2-oxo-1,3-oxazolidin-5-yl]methyl}-5-chloro-2-thiophenecarboxamide (from Example 149) is dissolved in 27 ml of tetrahydrofuran and admixed with 0.2 g (1.29 mmol) of 5-chlorovaleryl chloride and 0.395 ml (2.83 mmol) of triethylamine. The mixture is concentrated under reduced pressure and chromatographed over silica gel using a toluene/ethyl acetate=1:1→ethyl acetate gradient. This gives 315 mg (52% of theory) of a solid.
