Reaction Steps

To a solution of racemic 3-((5-fluoro-2-(5-fluoro-1-tosyl-1H-pyrrolo[2,3-b]pyridin-3-yl)pyrimidin-4-yl)amino)-4,4-dimethylpentan-1-ol, 82a, (0.187 g, 0.363 mmol) in dioxane (4 mL) was added LiOH (0.91 mL of 2 M solution, 1.81 mmol). The reaction mixture was heated at 100° C. for 2 hours. The mixture was diluted with water (30 mL) and extracted twice with EtOAc. The combined organic phases were washed with brine, dried (MgSO4), filtered and concentrated in vacuo. The crude residue was washed with Hexanes to afford 76 mg of the desired product: 1H NMR (300 MHz, CDCl3) δ 10.42 (s, 1H), 8.47 (dd, J=9.3, 2.7 Hz, 1H), 8.13 (d, J=11.2 Hz, 1H), 8.10 (s, 1H), 8.04 (d, J=3.2 Hz, 1H), 4.89 (d, J=9.0 Hz, 1H), 4.26 (t, J=9.9 Hz, 1H), 3.65 (d, J=9.2 Hz, 1H), 3.54 (td, J=11.4, 2.9 Hz, 1H), 2.17-1.99 (m, 1H), 1.40 (dd, J=14.0, 11.9 Hz, 1H), 0.96 (d, J=18.4 Hz, 9H), 0.90-0.73 (m, 1H); LCMS Gradient 10-90%, 0.1% formic acid, 5 minutes, C18/ACN, (M+H) 362.
