To a solution of 2-((1S,3S)-3-(5-fluoro-2-(5-fluoro-1-tosyl-1H-pyrrolo[2,3-b]pyridin-3-yl)pyrimidin-4-ylamino)-1-hydroxycyclohexyl)ethanenitrile, 69b, (0.14 g, 0.26 mmol) in methanol (10 mL) was added sodium methoxide (0.06 g, 0.26 mmol). After stirring at room temperature for 2 minutes, the reaction mixture was diluted into EtOAc and brine. The separated organic phase was dried over MgSO4, filtered, and concentrated in vacuo. The resulting residue was purified by silica gel chromatography (10% MeOH/CH2Cl2) to afford 46 mg of desired product: 1H NMR (300.0 MHz, MeOD) δ 8.65 (dd, J=2.8, 9.6 Hz, 1H), 8.19 (s, 1H), 8.14 (dd, J=2.0, 2.5 Hz, 1H), 7.98 (d, J=4.1 Hz, 1H), 4.66 (dd, J=8.0, 15.8 Hz, 1H), 2.64 (s, 2H), 2.20 (d, J=12.6 Hz, 2H), 2.01 (dd, J=3.4, 9.8 Hz, 2H), 1.84-1.75 (m, 1H), 1.63-1.47 (m, 2H), 1.33 (dd, J=3.6, 12.4 Hz, 1H) ppm; LCMS RT=2.31 (M+H) 385.45.
