Reaction Steps
To a solution of 1H-benzotriazole-5-carboxylic acid (1.00 g, 6.13 mmol) in 30 mL of dry tetrahydrofuran was added lithium aluminum hydride (0.47 g, 12 mmol) under nitrogen at 0° C. After the reaction mixture was stirred at 70° C. for 90 h, saturated Na2SO4 aqueous solution was added carefully at 0° C. After the solution was stirred at room temperature for 30 min, a sufficient amount of Na2SO4 was added with additional stirring for drying. After filtration, the filtrate was concentrated in vacuo, and the residue was purified by silica gel column chromatography (chloroform/methanol=97/3 to 80/20) to obtain (1H-benzoimidazol-5-yl)methanol as a pale yellow solid (143 mg, 16%).
