Synthetic Route of 39603-24-2, A common heterocyclic compound, 39603-24-2, name is 5,7-Dimethylindoline-2,3-dione, molecular formula is C10H9NO2, 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: To a 25 ml round bottom flask, a mixture of isatin / acenaphthoquinone / 2-hydroxynaphthoquinone/ ninhydrin (1 mmol), o-phenylene diamine (1 mmol) in ethanol (95 %, 10 mL) and sulfamic acid (20 mol %) was added. The reaction mixture was stirred at ambient temperature for time mentioned in Table II, monitored by TLC. After completion of reaction, the mixture was filtered washed with ethanol and dried to furnish the desired pure products in high yields.
The synthetic route of 39603-24-2 has been constantly updated, and we look forward to future research findings.
