Reaction Steps
To a stirred, cold (0° C.) mixture of 4-amino-3-isopropylamino-benzoic acid (11 g) in 120 mL of 6 N hydrochloric acid was added drop-wise a solution of 5.9 g of sodium nitrite in 40 mL of water. After 2 hours the solids were collected by filtration, washed with water, and dried to give 9 grams of 3-isopropyl-3H-benzotriazole-5-carboxylic acid.
