Participants

Reaction Steps

A mixture of (S)-(-)-2,2-dichloro-N-[[2-oxo-3-[3-fluoro-4-[1-[(acetoxy)acetyl]-4-piperidinyl]phenyl]-5-oxazolidinyl]methyl]acetamide (EXAMPLE 32, 110 mg) and anhydrous potassium carbonate (60 mg) in methanol (8.8 mL) is stirred under N2 at ambient temperature for one hour and then concentrated under reduced pressure and chromatographed on silica gel (70-230 mesh, 10 g), eluting with methanol/chloroform (10/90). Pooling and concentration of those fractions with an Rf =0.41 by TLC (methanol/chloroform, 10/90), repurification by radial chromatography (2000μ silica gel plate) eluting with methanol/methylene chloride, and trituration with chloroform/diethyl ether gives the title compound, NMR (CDCl3, 400 MHz) 7.46, 7.39, 7.15, 5.99, 4.84, 4.74, 4.22, 4.09, 3.77, 3.61, 3.10, 2.79, 1.89, 1.65 δ.
