Procedure
Ammonium hydroxide (4.15 ml, 75 mmol) was added slowly to a solution of 1-hydroxybenzotriazole (10 g, 74 mmol) in tetrahydrofuran (100 ml) at 0° C. (ice-bath) and stirred for 2 hrs. Filtration and washing with tetrahydrofuran gave ammonium 1H-1,2,3-benzotriazol-1-olate (10.57 g) as a white solid.
