Synthetic Route of 63237-88-7, 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 63237-88-7 as follows.
General procedure: A solution of P(OMe)3 (1.5mmol) in DCM (10mL) was cooled with an ice bath, then I2 (1.5mmol) was added. After the solid iodine was completely dissolved, corresponding acid (1.2mmol) and Et3N (3.0mmol) were added in sequential order, and the solution was stirred for 15min in a cooling bath. Intermediate 5 (1.0mmol) was added and the mixture was stirred for 15min. After removing the cooling bath, the reaction mixture was stirred for 3.5hat room temperature, then diluted with saturated aqueous NaHCO3 and extracted with DCM (10mL) three times. The combined organic layer was sequentially washed with water and brine, dried with anhydrous Na2SO4, and concentrated in vacuo. The crude was purified by column chromatography with DCM/methanol (100:1 to 50:1, v/v) to give the product as a white solid.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,63237-88-7, its application will become more common.
