Procedure

30% H2O2 (10 mL) was added to the solution of 1-(5-cyclopropyl-3-(2-phenyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyrimidin-4-ylamino)-1H-pyrazol-1-yl)ethanone (200 mg, 0.45 mmol, 1.0 eq) in THF (5 mL) at 0° C. The mixture was stirred for 1 h and water was added. The solid was collected and dissolved in methanol (8 mL). To the solution was added 5 N NaOH (4 mL). The mixture was stirred for 2 h at room temperature and concentrated. To the residue was added ethanol and EtOAc. The emerged solid was filtered off. The filtrate was concentrated and the residue was recrystallized with CH2Cl2 and ethyl ether to give 4-(5-cyclopropyl-1H-pyrazol-3-ylamino)-2-phenylpyrimidin-5-ol (Compound 55) (10 mg, 8% over 2 steps). LC-MS (m/z)=294.0 [M+H]+. 1H NMR (400 MHz, DMSO-d6): δ 0.69-0.74 (m, 2H), 0.93-0.98 (m, 2H), 1.85-1.89 (m, 1H), 6.52 (bs, 1H), 7.40-7.47 (m, 3H), 7.93 (s, 1H), 8.22 (d, J=7.6 Hz, 2H), 8.41 (bs, 1H), 10.43 (bs, 1H), 12.09 (bs, 1H).
