실험 절차

To a solution of 4-methylphenylboronic acid (34 g, 0.25 mol) in aqueous sodium hydroxide (0.5 N, 1000 mL) was added potassium permanganate (83 g, 0.53 mol) while keeping the temperature at 35-40° C. After the addition the reaction was filtered and the filtrate acidified with concentrated hydrochloric acid (65 mL). The product was filtered off. A yield of 29.6 g was obtained. M.p. 228° C.
