Versuchsvorschrift
A solution of tetrabutylammonium fluoride 1M in THF (1 mL; 1 mmol) was added to a solution of N-(2-(5-chloro-2-(triethylsilyl)-1H-pyrrolo[2,3-b]pyridin-3-yl)ethyl)-5-(2,5-difluorobenzyl)isoxazole-3-carboxamide (0.105 g, 0.198 mmol) in THF (5 mL). The mixture was stirred overnight at room temperature and was evaporated. The residue was dissolved in dichloromethane, and the organic solution was washed with water and was concentrated under reduced pressure. The crude material was purified twice by flash chromatography on silica gel (eluent: 0 to 40% of ethyl acetate in dichloromethane) to give 0.019 g (22%) of N-(2-(5-chloro-1H-pyrrolo[2,3-b]pyridin-3-yl)ethyl)-5-(2,5-difluorobenzoyl)isoxazole-3-carboxamide as a white solid.
