Ethyl Acetate → (2-(5-chloro-1-(phenylsulfonyl)-1H-pyrrolo[2,3-b]pyridin-3-yl)-5-fluoropyrimidin-4-ylamino)-1-methylcyclohexanol

Temperature

0 °C

To a cold (0° C.) solution of 3-[[2-[5-chloro-1-(p-tolylsulfonyl)pyrrolo[2,3-b]pyridin-3-yl]-5-fluoro-pyrimidin-4-yl]amino]cyclohexanone, 28a, (0.47 g, 0.92 mmol) in THF (5 mL) was added methylmagnesium bromide (3.30 ml of 1.4M solution, 4.58 mmol). The reaction mixture was stirred at 0° C. for 1 h. The reaction mixture was diluted with ethyl acetate and aqueous saturated NH4Cl solution. The organic phase was separated, dried (MgSO4), filtered and concentrated in vacuo. The products were purified by silica chromatography with DCM and methanol, two products were eluded with 95% DCM and 5% methanol no separation. The two diastereomers were taken on as a mixture without further purification.
