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
To the Butyl acetate solution of N- alkylated indoline derivative obtained in the reaction step, 35mL of butyl acetate and tartaric acid 1.3 g were added and stirred, and then heated to around 80 C andstirred. After confirming that the tartaric acid was dissolved, then cooled toabout 20 C and stirred for 2 hours. The precipitated solid was collected by filtration, and the resulting wet material was dried under reduced pressure in the vicinity of 40 , to obtain N- alkylated indoline derivative tartrate salt4.6g (purity 96.1%, dialkyl body content 0. 38%) (64.7% yield from the indoline derivative tartrate salt) as a white crystalline.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, (R)-3-(5-(2-Aminopropyl)-7-cyanoindolin-1-yl)propyl benzoate (2R,3R)-2,3-dihydroxysuccinate, other downstream synthetic routes, hurry up and to see.
