Reaction Steps

30 mg of 60 percent NaH in liquid paraffin are added under inert conditions to 5 ml of DMSO, and the mixture is heated at 75° C. for 30 min until gas evolution ceases. Then 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-thiophenecarboxamide (from Example 161) in 5 ml of methylene chloride is added dropwise, and the mixture is stirred at room temperature overnight. The reaction is stopped and the mixture is added to 100 ml of water and extracted with ethyl acetate. The evaporated organic phase is chromatographed on an RP-8 column and eluted with acetonitrile/water. 20 mg (7.5% of theory) of the target compound are obtained.
