反应详情

Into a round bottom flask was added {3-[(5-chloro-1H-pyrrolo[2,3-b]pyridin-3-yl)-hydroxy-methyl]-2,4-difluoro-phenyl}-carbamic acid benzyl ester (6, 1.01 g, 2.28 mmol) in 5.00 mL of tetrahydrofuran. Dess-Martin periodinane (1.20 g, 2.89 mmol) was added in portions. The reaction mixture was stirred at room temperature for 10 minutes, then poured into water and extracted with ethyl acetate. The organic layer was washed with brine, dried over sodium sulfate, filtered and the filtrate concentrated under vacuum and purified by silica gel chromatography to give the desired compound (7, 914 mg, 91%). MS (ESI) [M+H+]+=442.
