With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.28418-88-4,4-Iodoisobenzofuran-1,3-dione,as a common compound, the synthetic route is as follows.
(1-1) Production of N-(4-methyl-3-trifluoromethylisoxazol-5-yl)-3-iodophthalimide In 20 ml of acetic acid, 0.6 g of 3-iodophthalic anhydride and 0.44 g of 5-amino-4-methyl-3-trifluoromethyl-isoxazole were dissolved and reacted for 9 hours with heating under reflux. After completion of the reaction, the solvent was distilled off under reduced pressure, and the residue was dissolved in ethyl acetate, washed with dilute hydrochloric acid, saturated aqueous solution of sodium bicarbonate and saturated aqueous solution of sodium chloride, and then dried on sodium sulfate. After distilling off the solvent under reduced pressure, the residue was purified by silica gel column chromatography using a 3/1 mixture of hexane and ethyl acetate as an eluent to obtain 0.71 g of the objective product. Property: m.p. 105C; Yield: 69%
28418-88-4, 28418-88-4 4-Iodoisobenzofuran-1,3-dione 282071, abenzofuran compound, is more and more widely used in various fields.
