Synthetic Route of 115473-15-9, 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 115473-15-9 as follows.
A reaction flask equipped with a stirrer, a condenser and a thermometer was charged with Intermediate II-214.9 g,This was dissolved in 40 ml of trichloromethane, 15.0 g of triethylamine was added under stirring,9.5 g of 5,6,7,7a-tetrahydrothieno [3,2-c] pyridin-2 (4H) -one hydrochloride were added portionwise to the reaction system,After completion of the dropwise addition, the reaction was continued at 0 C for 3 hours (the plate showed complete reaction).The reaction solution was washed with 3 x 20 ml of water, the chloroform layer was separated,Dried over anhydrous sodium sulfate, filtered, evaporated to dryness under reduced pressure,To give 12.0 g of a pale yellow solid product (HPLC: 98.9%),
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,115473-15-9, its application will become more common.
