Procedure

To a suspension of N-(2,6-dichloro-3,5-dimethoxy-phenyl)-acetamide (f) (6.50 g, 24.61 mmol) in a mixture of EtOH (80 mL) and water (30 mL), KOH (20 g) is added, and the mixture is stirred 2 days at 80° C. After the solvent (EtOH) is removed under vacuum, water (˜15 mL) is added, and a white solid is collected by filtration and washed with water and dried to give final product g: 1H NMR 600 MHz (CDCl3) δ 6.03 (s, 1H), 4.55 (s, 2H), 3.88 (s, 6H); MS m/z 222.00 (M+1).
