As a common heterocyclic compound, it belongs to thiazines compound, name is 3-Bromo-10H-phenothiazine, and cas is 3939-23-9, its synthesis route is as follows.,3939-23-9
2, under nitrogen protection will be prepared in step 1 p-phenylenediamine and phenothiazine derivatives according to 1:1 molar ratio was added to toluene, while adding potassium tert-butyl alcohol and palladium acetate as a catalyst,The reaction was heated to 80 C for 3 hours and then cooled to room temperature. The reaction was filtered,The filtrate was washed with dichloromethane and then the solvent was evaporated to dryness. The crude product was repeatedly washed with methanol and acetone,The product is obtained after purification by column chromatography.
With the complex challenges of chemical substances, we look forward to future research findings about 3939-23-9,belong thiazines compound
