Reaction Steps

Acetic anhydride (27 mL) was added to 2,4-dichloro-5-aminobenzoic Acid 1-3 (8.0 g, 0.041 mol) in glacial AcOH (150 mL). The solution was stirred at room temperature for 30 min and concentrated to yield the desired acetamide 1-4 as a white solid (9.6 g, 96%). 1H NMR (400 MHz, CD3OD) δ2.19 (s, 3H), 7.62 (s, 1H), 8.32 (s, 1H).
