To a solution of (S)-4-amino-6-(1-(6-fluoro-1-(5-fluoropyridin-3-yl)-1H-benzo[d]imidazol-2-yl)ethylamino)pyrimidine-5-carbonitrile (0.040 g, 0.10 mmol) in DMSO (1.02 mL) was added potassium carbonate (0.017 g, 0.122 mmol) followed by hydrogen peroxide (31% in water, 0.635 mL, 6.42 mmol). After stirring for 2 h the solution was poured into water and extracted with EtOAc. Organic extracts were concentrated and purified by MPLC (eluted with 0-100% (1:10:90 NH4OH:MeOH:DCM) in DCM) to afford 4-amino-6-4(1S)-1-(6-fluoro-1-(5-fluoro-3-pyridinyl)-1H-benzimidazol-2-yl)ethyl)amino)-5-pyrimidinecarboxamide as a white solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 1.51 (d, J=6.85 Hz, 3H) 5.34 (quin, J=6.94 Hz, 1H) 6.57 (s, 2H) 7.04-7.22 (m, 2H) 7.43 (br. s., 2H) 7.67-7.80 (m, 2H) 7.92 (d, J=7.63 Hz, 1H) 8.21 (dt, J=9.29, 2.10 Hz, 1H) 8.71 (s, 1H) 8.81 (d, J=2.74 Hz, 1H).
