A cooled (0° C.) solution of the minor isomer 3-(1H-1,2,3-triazol-1-yl)benzoic acid (210 mg; 1.11 mmol) in anh. THF (3 ml) was treated dropwise with a BH3.THF (1.0 M in THF; 2.77 ml; 2.77 mmol), and this mixture was stirred at 0° C., under nitrogen, for 1 h, and then at rt for 17 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-(1H-1,2,3-triazol-1-yl)phenyl)methanol as a pale yellow solid. LC-MS (conditions A): tR=0.38 min.; [M+H]+: 176.18 g/mol.
