Electric Literature 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: The mixture of 4-bromophthalimide (225 mg, 1 mmol), 4-RPhSH(3 mmol), K2CO3 (136 mg, 1 mmol) and CuI (10 mg) was added to DMF (10 mL). The solution was heated at 130 C for 6 h under the protection of nitrogen. After cooled, water (30 mL) was added and the precipitation was filtered, washed with water. The product was purified by column chromatography on silica gel using dichloromethane/acetone (60:1).
The synthetic route of 6941-75-9 has been constantly updated, and we look forward to future research findings.
