Acetic anhydride-pyridine-dichloromethane solution (1 to 1.5 to 3, 4 mL) was added to BAL resin immobilized 5-(S)-aminomethyl-3-[4′-dimethoxymethyl-3′-fluorophenyl]-oxazolidine-2-one, and the mixture was agitated for ca. 2 h (until negative ninhydrine test indicated completion of the acylation). The resin was filtered, washed liberally with methanol and dichloromethane and dried under vacuum.
