Adding a certain compound to certain chemical reactions, such as: 40117-63-3,Quinuclidine-4-carboxylic acid hydrochloride, 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 40117-63-3,40117-63-3
Step 8: (S)-4- ((1- (5- (2-methoxyquinolin-1-ium-3-yl)oxazol-2-yl)- 7- (methylamino)- 7-oxoheptyl)carbamoyl)quinuclidin-1-ium mono L-tartrate salt (F8)A solution of 4-carboxyquinuclidin-1-ium chlorhydrate (1.3 eq.) in DMF (0.1 M) was treated with HOBt (1.3 eq.), EDC HC1 (1.3 eq.) and DIPEA (1.3 eq.). The reaction mixture was stirred at room temperature for 10 minutes and then added to F7. The reaction was stirred for at RT for 48 h, filtered and directly purified by RP-HPLC (Acetonitrile/H20 + 0.1 % TFA). The product was obtained as TFA salt which was partitioned between DCM and sat. aq. NaHCO3. Theorganic phase was separated dried over Na2504 and concentrated under reduced pressure. The resulting solid was dissolved in acetonitrile/H20 (1:1) and treated with L-tartaric acid (1 eq.). The resulting solution was lyophilized to obtain the title compound. MS (ESj C29H37N504: 520 (M+H).
According to the analysis of related databases, 40117-63-3, the application of this compound in the production field has become more and more popular.
