Participants

Reaction Steps

To a cold (0° C.) solution of racemic N-(4,4-dimethyl-1-((2-nitrophenyl)selanyl)pentan-3-yl)-5-fluoro-2-(5-fluoro-1-tosyl-1H-pyrrolo[2,3-b]yridin-3-yl)pyrimidin-4-amine, 88a, (1.01 g, 1.45 mmol) in chloroform (15 mL) was added mCPBA (0.40 g of 77%, 1.79 mmol). After stirring for 1 hour at room temperature, the mixture was diluted with dichloromethane (100 mL) and the resulting solution was washed with aqueous sodium bicarbonate solution. The organic phase was dried (MgSO4), filtered and concentrated in vacuo. The crude residue was purified by silica gel chromatography (0 to 100% EtOAc/Hexanes) to afford 623 mg of the desired product: LCMS Gradient 10-90%, 0.1% formic acid, 5 minutes, C18/ACN, (M+H) 496.76.
