Procedure

Methylmagnesium chloride 3.0 M in THY (0.3 mL) was added dropwise to a mixture of 1-(5-bromopyridin-2-yl)ethanone (100 mg, 0.5 mmol) in tetrahydrofuran (10 mL) at 0° C. After stirring for 1 h at room temperature, the reaction was quenched with 1 N NH4Cl and was extracted with EtOAc. The combined organic layer was washed with brine and dried over MgSO4, concentrated to give crude 2-(5-bromopyridin-2-yl)propan-2-ol (0.1 g, 100%). LCMS calculated for C8H11BrNO (M+H)+: m/z=215.9, 217.9; found: 215.8, 217.8.
