Sodium borohydride → 4-(2H-1,2,3-Triazol-2-yl)benzenemethanol

Participants

Reaction Steps

To a solution of 42.26 g (244 mmol) of 4-[1,2,3]-triazol-2-yl-benzaldehyde in 140 ml of THF and 420 ml of MeOH, 9.23 g (244 mmol) of NaBH4 are added portionwise at 0-5° C. and the mixture is stirred for 30 min. at the same temperature. The reaction is quenched with sat. NH4Cl at 0-5° C. and the mixture is extracted with AcOEt. The combined extracts are washed with brine, dried over MgSO4 and concentrated under reduced pressure to give the title compound as a colorless solid.
