To a solution of methyl 5-bromo-6-methyl-3-pyridinecarboxylate (76 mg, 0.330 mmol) in DCM (1.5 ml), DIBAL-H (1.5 M solution in toluene, 0.661 ml, 0.991 mmol) was added dropwise at −78° C. under N2. The reaction mixture was allowed to warm to rt and stirred overnight. To this solution was added saturated, aqueous NaK-tartrate solution followed by DCM. The organic phase was separated, dried and concentrated to afford 56 mg of (5-bromo-6-methyl-3-pyridinyl)methanol (56 mg, 84%) pure enough to be used in the next step.
