After oxone (potassium peroxymonosulfate, from Sigma-Aldrich®; 12.28 g, 20.0 mmol) had dissolved completely in water (100 mL), potassium carbonate (4.14 g, 30 mmol) was added slowly to neutralize the solution to a weak acidity. The solution was added quickly into a solution of 4′-aminoacetanilide (from Sigma-Aldrich®; 1.50 g, 10.0 mmol) in water (150 mL). The mixture immediately turned green, and greenish-gray solids started to fall out of solution. After the mixture had been stirred for another 10 minutes, the precipitates were collected on a filter funnel, air dried, and recrystallized from hot ethanol. Two batches of products were collected to give a total yield of 1.06 g (65%) greenish crystals, mp 179-180° C. (lit. 179-180° C.).
