Reaction Steps
Under inert conditions, 5 ml of DMSO are admixed with 30 mg of NaH (60% in paraffin oil), and the mixture is heated at 75° C. for 30 min, until the evolution of gas has ceased. A solution of 290 mg (0.617 mmol) of 5-chloro-N-[((5S)-3-{4-[(5-chloropentanoyl)amino]phenyl}-2-oxo-1,3-oxazolidin-5-yl)methyl]-2-thiophene-carboxamide (from Example 161) in 5 ml of methylene chloride is then added dropwise, and the mixture is stirred at room temperature overnight. The reaction is terminated and the mixture is poured into 100 ml of water and extracted with ethyl acetate. The evaporated organic phase is chromatographed on an RP-8 column and the product is eluted with acetonitrile/water. This gives 20 mg (7.5% of theory) of the target compound.
