Participants

Reaction Steps

10 g (24.8 mmol) of 2-[2-fluoro-4-[(5R)-5-(azidomethyl)-2-oxo-3-oxazolidinyl]phenyl]-hexahydro-1H-spiro[cyclopenta[c]pyrrol-5,2′-[1,3]dioxolane] prepared in the step 9 was dissolved in 100 ml of ethyl acetate, and 1 g of 10% palladium/active carbon, 4.01 ml (45.6 mmol) of pyridine and 3.5 ml (37.2 mmol) of acetic anhydride were added, and then, the mixture was stirred for 5 hours under hydrogen gas balloon. After the reaction was completed, the reaction mixture was filtered to remove solid and concentrated under reduced pressure. The concentrate was separated by column chromatography to obtain 5.30 g (51%) of the title compound, of which NMR data is as follows.
