Xenon difluoride → trans-N-{[2-(3-fluoro-2-methyl-2H-indazol-4-yl)cyclopropyl]methyl}acetamide

Participants

Reaction Steps

To a solution of N-{[(1R,2R)-2-(2-methyl-2H-indazol-4-yl)cyclopropyl]methyl}acetamide (100 mg, 0.411 mmol) in acetonitrile (4.1 mL) was added xenon difluoride (76.5 mg, 0.452 mmol), and the mixture was stirred at room temperature for 4 hr. The reaction solution was diluted with ethyl acetate, washed with saturated aqueous sodium hydrogen carbonate is solution and saturated brine, and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (NH, ethyl acetate/hexane=50/50→100/0) and preparative TLC (methanol/ethyl acetate=10/90) to give the title compound (13.9 mg, yield 11%).
