Versuchsvorschrift

Methyl 2-hydroxypyridine-3-carboxylate (1.48 g) and potassium carbonate (2.23 g) were added to a solution of tert-butyl (6S,7R)-7-(4-chloro-3-fluorophenyl)-6-{[(methylsulfonyl)oxy]methyl}-1,4-oxazepane-4-carboxylate (3.53 g) in 1,2-dimethoxyethane (70 ml). The reaction mixture was stirred at 80° C. overnight. The reaction mixture was concentrated under reduced pressure, water was added to the residue, and the mixture was extracted with ethyl acetate. The extract was washed with brine, and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography to give the title compound (2.88 g).
