5-Bromo-3-pyridinecarboxaldehyde → (5-Bromo-3-pyridinyl)methanol

Participants

Reaction Steps

To a solution of 5-bromonicotinaldehyde (XXV) (2.05 g, 11.0 mmol) in MeOH (85 mL) was added NaBH4 (832 mg, 21.99 mmol). The reaction was stirred at room temperature for 1 h. The reaction was quenched with saturated aqueous NH4Cl (5 mL). The reaction was concentrated under vacuum and the residue was partitioned between saturated aqueous NH4Cl/EtOAc. The organic layer was separated, washed with water, brine, dried over MgSO4 and concentrated under vacuum to yield crude (5-bromopyridin-3-yl)methanol (XLV) as a golden oil (1.54 g, 8.2 mmol, 74% yield). The product was used without further purification. ESIMS found for C6H6BrNO m/z 188 (M+H).
