To a solution of 5-[(4-ethenylphenyl)oxy]-2-(trifluoromethyl)pyrimidine (100 mg, 0.376 mmol) and 9-BBN (1.503 mL, 0.751 mmol) in THF (5 mL) under nitrogen, which was stirred overnight was added NaOH (0.501 mL, 1.503 mmol) and H2O2 (0.460 mL, 4.51 mmol). The mixture was heated at 60° C. for 1 h, and then quenched with NH4Cl sat. solution after cooling. The organic layer was separated and washed with Na2SO3 solution and brine. The organic layer was dried by Na2SO4. Concentration then afforded the title compound (80 mg, 0.281 mmol, 74.9% yield). LCMS: rt=2.82 min, [M+H]=285
