To a solution of tert-butyl N—[N-[(1R,3S)-3-[[5-fluoro-2-[5-fluoro-1-(p-tolylsulfonyl)pyrrolo[2,3-b]pyridin-3-yl]pyrimidin-4-yl]amino]cyclohexyl]carbamimidoyl]carbamate, 70c, (0.100 g, 0.156 mmol) in THF (20 mL) was added sodium methoxide (0.033 g, 0.156 mmol) at room temperature. After 1 minute, the reaction mixture was diluted into EtOAc and aqueous saturated NaHCO3 solution. The organic phase was dried over MgSO4, filtered and the solvent was removed under reduced pressure. The resulting residue was purified by silica gel chromatography to afford 95 mg of the desired product. To 10 ml MeOH solution of the product was added hydrochloride/IPA (0.031 mL of 5 M solution, 0.156 mmol). The reaction mixture was stirred at room temperature for 1 hour after which the solvent was removed under reduced pressure to afford the product, as hydrochloride salt: 1H NMR (300 MHz, MeOD) δ 8.63 (s, 1H), 8.40 (dd, J=9.1, 2.7 Hz, 1H), 8.36 (s, 1H), 8.32 (d, J=5.5 Hz, 1H), 4.46 (d, J=11.7 Hz, 1H), 3.78-3.53 (m, 1H), 2.41 (d, J=11.7 Hz, 1H), 2.28 (d, J=12.0 Hz, 1H), 2.18-1.98 (m, 2H), 1.69 (dd, J=23.6, 11.8 Hz, 2H), 1.56-1.28 (m, 2H); LCMS RT=1.45 (M+H) 387.06.
