Procedure

LiOH (0.118 mg, 4.927 mmol) was added to a solution of ethyl 3-(5-fluoro-2-(5-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl)pyrimidin-4-ylamino)-3-(1-methylcyclohexyl)-propanoate, 77, (0.23 g, 0.49 mmol) in water (5 mL) and THF (5 mL). The solution was stirred at 95° C. for 18 hours and then cooled to room temperature. The solvent was removed under reduced pressure. The residue was diluted with water (10 mL) and neutralized with 2N HCl. The resulting precipitate was extracted with EtOAc (3×10 mL). The organic phase was dried (MgSO4), filtered and concentrated in vacuo to afford 210 mg of the desired product as an off-white solid: 1H NMR (400 MHz, CD3OD) δ 8.78 (dd, J=9.7, 2.7 Hz, 1H), 8.16 (s, 2H), 7.99 (d, J=4.1 Hz, 1H), 5.20 (d, J=9.9 Hz, 1H), 2.86-2.69 (m, 1H), 2.53 (dd, J=14.7, 11.0 Hz, 1H), 1.76-1.56 (m, 2H), 1.53 (m, 4H), 1.29 (m, 4H), 1.02 (s, 3H); LCMS Gradient 10-90%, 0.1% formic acid, 5 minutes, C18/ACN, Retention Time=2.20 minutes (M+H) 416.27.
