Application of 3029-64-9, In the chemical reaction process,reaction time,type of solvent,can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product.An updated downstream synthesis route of 3029-64-9 as follows.
8.79 g (35 mmol) of isopropyl carbazole was added to a 250 ml three-necked flask, and 100 ml of N,N-dimethylformamide was added as a reaction solvent in an ice bath.Stir on a magnetic stirrer for 10 min. 0.72 g (30 mmol) of NaH was added portionwise to the reaction flask and stirring was continued for 1 h.4.97 g (10 mmol) of 2,4,6-trichloro-5-cyanopyrimidine was dissolved in 40 ml of N,N-dimethylformamide solution, and added dropwise to the reaction system. After the addition, at room temperature The reaction was carried out for 24 h. After the reaction was completed, the reaction solution was poured into 200 ml of 10percent diluted hydrochloric acid, and the mixture was filtered under reduced pressure, washed with water and dried, and the crude product was obtained from petroleum ether and dichloromethane (PE: DCM=10: 1) Pass the column for the mobile phase. Obtained 7.98 g of a white solid powder in a yield of50.2percent.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,3029-64-9, its application will become more common.
