Triphenylphosphine (0.130 g, 0.496 mmol) was added to a mixture of BAL aldehyde resin (0.57 g, 0.165 mmol) and 5-(S)-azidomethyl-3-[4′-dimethoxymethyl-3′-fluorophenyl]-oxazolidine-2-one (0.154 g, 0.496 mmol) in THF (3 ml) at room temperature. The mixture was stirred at room temperature for 2 h, and then at 75° C. for 16 h. The mixture was cooled to room temperature, and 1 M sodium cyanoborohydride in THF (0.99 ml, 0.992 mmol) was added in one portion. The reaction mixture was agitated for 8 h. The resulting amine resin was washed liberally with methanol and dichloromethane and dried under vacuum.
