실험 절차
To a solution of o-aminophenylboronic acid (6.73 g, 49.1 mmoles) in dioxane (100 ml) is added acetic anhydride (25.1 g, 246 mmoles). The reaction is heated at 100° C. for 17 hours. After cooling, the reaction volatiles are removed under reduced pressure to leave a thick yellow gel, which after chromatography affords o-N-acetylaminophenylboronic acid (7.33 g).
