Synthetic Route of 6941-75-9, These common heterocyclic compound, 6941-75-9, name is 5-Bromoisoindoline-1,3-dione, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
General procedure: A mixture of 2-(7-methoxynaphthalen-1-yl)ethanamine (compound 3, 101 mg, 0.5 mmol), sodium acetate (82 mg, 1.0 mmol) and cyclic anhydrides 1.0 mmol) in 5mL acetic acid was heated to reflux for 3 h in a round bottomed flask. After the completion of reaction (as evidenced by TLC), the resulting mixture was concentrated under reduced pressure and washed with ethyl acetate (10 mL×3), then the concentrated organic layer was purified by column chromatography on silica gel to obtain pure product.
The synthetic route of 6941-75-9 has been constantly updated, and we look forward to future research findings.
