실험 절차

To a solution of 0.50 g (1.27 mmol) [(6R,7S)-2-fluoro-6-methyl-8-oxo-9-(2,2,2-trifluoro-ethyl)-6,7,8,9-tetrahydro-5-oxa-9-aza-benzocyclohepten-7-yl]-carbamic acid tert-butyl ester in 5 ml tetrahydrofurane were added 1.89 g ortho-phosphoric acid. The mixture was stirred at room temperature for 2 days. Extraction with ethylacetate/water and chromatography on silicagel with dichloromethane/methanol 98/2 yielded 0.31 g (83%) (6R,7S)-7-amino-2-fluoro-6-methyl-9-(2,2,2-trifluoro-ethyl)-6,7-dihydro-9H-5-oxa-9-aza-benzocyclohepten-8-one, MS m/e (%): 293.1 (M+H+, 100).
