Sodium borohydride → (1-(5-bromopyridin-2-yl)-1H-imidazol-4-yl)methanol

Participants

Reaction Steps

To a suspension of 1-(5-bromopyridin-2-yl)-1H-imidazole-4-carbaldehyde (730 mg, 2.90 mmol) in MeOH (10 mL) at room temperature was added NaBH4 (134 mg, 3.53 mmol). The mixture was stirred for 30 min, during which time the suspension became clear. The solvent was removed in vacuo. The residue was partitioned between H2O and EtOAc. The organic phase was separated, washed with 5% NaHCO3, dried over Na2SO4, concentrated in vacuo to give (1-(5-bromopyridin-2-yl)-1H-imidazol-4-yl)methanol as a solid (520 mg).
