3939-23-9, 3-Bromo-10H-phenothiazine is a thiazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
2, under the protection of nitrogen will be prepared in step 1 aromatic diamine 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.
The synthetic route of 3939-23-9 has been constantly updated, and we look forward to future research findings.
