Adding a certain compound to certain chemical reactions, such as: 239463-85-5, name is (R)-3-(5-(2-Aminopropyl)-7-cyanoindolin-1-yl)propyl benzoate (2R,3R)-2,3-dihydroxysuccinate, belongs to indolines-derivatives compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 239463-85-5, Safety of (R)-3-(5-(2-Aminopropyl)-7-cyanoindolin-1-yl)propyl benzoate (2R,3R)-2,3-dihydroxysuccinate
3-{5-(2R)-2-aminopropyl}-7-cyano-{2,3-dihydro-1H-indol-1-yl}propylbenzoate(2R,3R)tartarate(Mono-tartaric acid salt of the compound of formula (II)),A mixture of potassium carbonate (80 g) and a mixed solvent of acetonitrile and dimethylacetamide (ACN / DMAC = 500 mL / 500 mL) was heated to 80 DEG C and stirred for 30 minutes. To the reaction mixture70 g of 2- [2- (2,2,2-trifluoroethoxy) phenoxy] ethyl methanesulfonate (compound of formula 3) and 9.70 g of KI were added,The reaction was carried out at the same temperature for 10 hours.The reaction mixture was cooled to room temperature, 1 L of ethyl acetate and 1.5 L of water were extracted.The organic layer obtained by layer separation was washed with 1 L of brine,After drying over 40 g of anhydrous MgSO4 for 30 minutes,After washing again with 200 mL of ethyl acetate, the solvent was removed by distillation.
