With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.942-06-3,4,5-Dichlorophthalic Anhydride,as a common compound, the synthetic route is as follows.
To a solution of 5,6-dichloroisobenzofuran-1,3-dione (2 g, 9.22 mmol) in xylene (10 ml), 2-aminoacetic acid (0.761 g, 10.14 mmol) was added, and the reaction was heated at 160¡ã C. for 40 hours. The precipitate that formed during the reaction was filtered, washed with water and hexanes and dried affording 2-(5,6-dichloro-1,3-dioxoisoindolin-2-yl)acetic acid (2.33 g, 8.50 mmol, 92percent yield).
942-06-3 4,5-Dichlorophthalic Anhydride 70334, abenzofuran compound, is more and more widely used in various.
