2-(4-bromo-3-oxobutyl)isoindoline-1,3-dione To a solution of 2-(3-oxobutyl) isoindole-1 ,3-dione (3.0 g, 13.81 mmol) in methanol (100 imL) was added bromine (2.43 g, 15.19 mmol) dropwise at 0C. The reaction mixture was stirred at the same temperature for 30 min and then at room temperature for 15 h. To the resulting clear solution was added concentrated sulfuric acid (10 M, 20 mL) and the resulting mixture was stirred at room temperature for 24 h. The precipitated solid was filtered and air- dried, afforded the desired product, 2-(4-bromo-3-oxobutyl)isoindoline-1 ,3- dione, as a white solid, (1 .85 g, 46% yield).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 2-(3-Oxobutyl)isoindoline-1,3-dione, other downstream synthetic routes, hurry up and to see.
