A cooled (0° C.) solution of the major isomer 3-(2H-1,2,3-triazol-2-yl)benzoic acid (500 mg; 2.64 mmol) in anh. THF (7 ml) was treated dropwise with a BH3.THF (1.0 M in THF; 6.60 ml; 6.60 mmol), and this mixture was stirred at 0° C., under nitrogen, for 1 h, and then at rt for 1.5 h. The resulting reaction mixture was then cooled to 0° C., and treated successively with MeOH (10 ml) and water (10 ml). The organic solvents were removed under reduced pressure, and the resulting aq. layer was extracted with DCM (3×10 ml). The mixed organic layers were washed with brine, dried over anh. MgSO4, filtered, and concentrated to dryness under reduced pressure. Purification by FC (DCM/MeOH=20/1) afforded (3-(2H-1,2,3-triazol-2-yl)phenyl)methanol as a colorless oil. LC-MS (conditions A): tR=0.51 min.; no ionisation.
