Reaction Steps

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° 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, 92% yield).
