To a solution of 1-(5-bromopyrimidin-2-yl)ethanone (99 mg, 0.50 mmol) in THF (10 mL) was added MeMgBr (1.65 mL, 4.95 mmol) at −78° C. under nitrogen. The formed solution was stirred at −78° C. for 20 min, quenched with satd aq NH4Cl, and extracted with EtOAc. The combined organic layer was dried over anhydrous Na2SO4 and concentrated to give an oil, which was purified by prep TLC (3:1 PE/EtOAc) to give 2-(5-bromopyrimidin-2-yl)propan-2-ol (50 mg, yield: 46.77%).
