6-((2-((4-(difluoromethoxy)phenyl)amino)pyrimidin-5-yl)methoxy)-3-(hydroxymethyl)benzo[d]oxazol-2(3H)-one (0.011 g, 0.026 mmol) was dissolved in a mixture of methanol (2 mL) and water (2 mL). The reaction mixture was sonicated for 15 min. Solvent was concentrated and the residue was lyophilized to give 6-((2-((4-(difluoromethoxy)phenyl)amino)pyrimidin-5-yl)methoxy)benzo[d]oxazol-2(3H)-one as a white solid (0.009 g, 87% yield). 1H NMR (400 MHz, DMSO-d6) δ ppm 4.99 (s, 2H) 6.82 (dd, J=8.53, 2.26 Hz, 1H) 6.94-7.32 (m, 5H) 7.79 (s, 2H) 8.59 (br. s., 2H) 9.84 (s, 1H) 11.42-11.50 (m, 1H). LCMS: R.T.=0.84 min; [M+H]+=401.0.
