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 1500-85-2 as follows., 1500-85-2
4-Amino-7H-pyrrolo [2,3-d] pyrimidine (0.60 g, 4.47 mmol) was weighedN-iodosuccinimide (1.51 g, 6.71 mmol)Dissolved in 100 ml of acetonitrile,And heated at 120 for 24h.After the reaction is completed, the solvent is evaporated,With dichloromethane mixed with water extraction,The organic phase was dried over anhydrous sodium sulfate and evaporated under reduced pressure.The residue was purified by column chromatography to give 0.96 g of a yellow solid (82.51% yield).
The chemical industry reduces the impact on the environment during synthesis 1500-85-2, I believe this compound will play a more active role in future production and life.
