実験手順

A mixture of (S)-(-)-N-[[3-[4-[1-[(benzyloxy)acetyl]-4-piperidinyl]phenyl]-2-oxo-5-oxazolidinyl]methyl]acetamide (EXAMPLE 18, 207 mg) and 10% palladium-on-carbon (100 mg) in methanol (9 mL) is shaken on a Parr apparatus under a hydrogen atmosphere at 40 psi for 20 hours, the catalyst is removed by filtration through Celite and the filtrate is concentrated under reduced pressure to give the crude product which is chromatographed on silica gel (230-400 mesh, 20 g), eluting with a gradient of methanol/methylene chloride (5/95-10/90). Pooling and concentration of those fractions with an Rf =0.26 by TLC (methanol/chloroform, 10/90) and recrystallization from methylene chloride/diethyl ether gives the title compound, mp 155-157° C.
