3-Bromo-10H-phenothiazine, cas is 3939-23-9, it is a common heterocyclic compound, the thiazines compound, its synthesis route is as follows.
Step 2, 132 mmol of 9-BBN was dissolved in THF at 0 C, 44 mmol of 1-2, Stirring for 15min, warming to 35 degrees Celsius, reaction 3h, and then transferred to the mixture containing 5-1 66mmoltetrakis(triphenylphosphine)palladium 0.88 mmol, sodium carbonate 132 mmol in toluene: ethanol: water = 4: 1: 1, and the temperature was raised to reflux temperature reaction24h. The crude product was passed through a silica gel column to give the product 20 mmol, 5-2.
As the rapid development of chemical substances, we look forward to future research findings about 3939-23-9
