実験手順
A mixture of (S)-(-)-4-[4-[5-[(acetylamino)methyl]-2-oxo-3-oxazolidinyl]phenyl]-3,6-dihydro-1(2H)-pyridinecarboxylic acid phenylmethyl ester (EXAMPLE 17, Step 5, 625 mg) and 10% palladium-on-carbon (300 mg) in methanol (100 mL) is shaken on a Parr apparatus under a hydrogen atmosphere at 40 psi for one hour and at 20 psi for 16 hours, the catalyst is removed by filtration through Celite and the filtrate is 6011.N DV1 concentrated under reduced pressure to give the title compound, mp 169-171° C.
