Procedure

80 mg (3R,4R)-4-(4-Benzyloxy-benzoyloxy)-3-[4-(4-fluoro-benzoyloxy)-benzoylamino]-azepane-1-carboxylic acid tert-butyl ester was dissolved in tetrahydrofuran. 10 mg 5% palladium on charcoal was added and the mixture hydrogenated at atmospheric pressure and room temperature for 2 hours. The catalyst was filtered on, the pad washed with tetrahydrofuran and the filtrate evaporated under reduced pressure. The residue was purified by chromatography on silica gel (10 g, AcOEt/Hexane 1:1 eluent) to afford 56 mg (80% yield) (3R,4R)-3-[4-(4-Fluoro-benzoyloxy)-benzoylamino]-4-(4-hydroxy-benzoyloxy)-azepane-1-carboxylic acid tert-butyl ester as a colorless foam
