反応手順
1.5 g of benzyl 3-{1-[3-(4-tert-butoxycarbonylaminomethylphenyl)-2-oxo-5-oxazolidinylcarbonyl]-4-piperazinyl}propionate are hydrogenated in 50 ml of DMF over 5% Pd/charcoal. After customary workup, the crude product is dissolved in a solvent mixture consisting of dichloromethane/methanol/glacial acetic acid (70:30:2) and chromatographed over silica gel. Trituration of the product with ether gives 3-{1-[3-(4-tert-butoxycarbonylaminomethylphenyl)-2-oxo-5-oxazolidinylcarbonyl]-4-piperazinyl}propionic acid, m.p. 76°-78°.
