Procedure

5-bromo-2,4-bis-methoxymethoxybenzoic acid methoxymethylester (IM3-d: 4.36 g, 11.9 mmol), ethanol (15 mL) and hydrazine monohydrate (0.96 mL, 29.8 mmol) were placed in a 100 mL eggplant shaped flask and stirred at 70° C. for 27 hours. After completing the reaction, the reaction mixture was extracted with methylene chloride, and the organic layer was washed with saturated sodium chloride solution and then concentrated under reduced pressure. The solid material thus obtained was suspended in hexane for purification to obtain the title compound (IM4-d: 1.8 g, 46%).
