To a solution of (S)-(1-(2-((5-fluoro-2-(5-fluoro-1-tosyl-1H-pyrrolo[2,3-b]pyridin-3-yl)pyrimidin-4-yl)amino)-3,3-dimethylbutyl)-1H-1,2,3-triazol-4-yl)methanol, 218a, (0.11 g, 0.19 mmol) in THF (5 mL) was added NaOMe (0.17 mL of 25% solution in MeOH, 0.75 mmol). After stirring the reaction mixture at room temperature for 30 minutes, the mixture was diluted into aqueous saturated NH4Cl solution (5 mL) and EtOAc (10 mL). The organic layer was separated, dried (MgSO4), filtered concentrated in vacuo. The crude product was purified by silica gel chromatography (0-10% MeOH/CH2Cl2) to afford 41 mg of the desired product as an off-white solid: 1H NMR (400 MHz, CD3OD) δ 8.51 (d, J=8.0 Hz, 1H), 8.16 (s, 1H), 8.09 (s, 1H), 7.93 (d, J=3.5 Hz, 1H), 7.38 (s, 1H), 5.08 (m, 1H), 5.00-4.90 (m, 1H), 4.74 (s, 2H), 4.60 (m, 1H), 1.2 (s, 9H); LCMS Gradient 10-90%, 0.1% formic acid, 5 minutes, C18/ACN, Retention Time=1.90 minutes (M+H) 429.26.
