실험 절차
A solution of ethyl 3-(2-(benzyloxymethyl)-2H-tetrazol-5-yl)benzoate (653 mg, 1.93 mmol) in THF (10 mL) was treated with a 0.5 M aqueous lithium hydroxide solution (5.8 mL, 2.9 mmol), and the reaction mixture was stirred for about 16 h. Analysis by LC/MS indicated that the reaction had not gone to completion, so the mixture was treated with a 0.5 M aqueous lithium hydroxide solution (1 mL, 0.5 mmol), and the reaction mixture was stirred for an additional 6 hours. The THF was removed under reduced pressure, and the aqueous solution was treated with 1 N HCl (3.5 mL, 3.5 mmol). The resulting mixture was extracted 3× with ethyl acetate, and the combined organic phases were dried over sodium sulfate and concentrated in vacuo to yield the title compound as a colorless powder which was used as-is in the next step.
