Application of 118289-55-7, 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 118289-55-7 as follows.
100.0 g of 6-Chloro-5-(2-chloroethyl) oxindole, 133.39 g of 3-(l-Piperazinyle)- 1,2-benzisothiazole hydrochloride, 105.94 g of sodium carbonate and 1500 mL of water were taken in round bottom flask and heated to 1000C to HO0C for 24-26 hours. The reaction mixture was cooled and maintained for 30 min. The solid was filtered and washed with water. The wet solid was further slurried with water followed by adjusting the pH of the reaction mass with dilute acetic acid to 6.0 to 7.5 and maintain the reaction mass for 1-2 hours. The solid was filtered and washed with water. The wet solid was treated with isopropanol 1100 mL in round bottom flask and heated at 750C to 850C for 2 hours. The reaction mixture was cooled, the obtained solid was filtered and washed with isopropanol. The wet solid was dried at 6O0C to 650C for 8-10 hours to obtain crude Ziprasidone base.
According to the analysis of related databases, 118289-55-7, the application of this compound in the production field has become more and more popular.
