Discovery of 22766-68-3

Adding a certain compound to certain chemical reactions, such as: 22766-68-3,Ethyl quinuclidine-4-carboxylate, 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 22766-68-3,22766-68-3

To a solution of ethyl 1-aza-bicyclo[2.2.2]octane-4-carboxylate (PCT2005104745) (9.610 g, 52.44 mmol) in THF (480 ml) at -780C was added borane-THF complex (73.41 ml,73.41 mmol) and the resulting solution was stirred at this temperature for 3.5 h. The reaction was quenched with slow addition of H2O (50 ml), warmed to RT, and allowed to stir for 45 min. The solution was diluted with EtOAc (100 ml), washed with brine (15 ml), extracted with EtOAc (3 x 50 ml), dried (Na2SO4) and evaporated. The crude product was purified on a CombiFlash companion using 0-50% EtOAc in cyclohexane as eluent to give a bright yellow solid.Yield: 7.236 g (70%)1 H NMR (400 MHz, CDCI3) delta = 4.15 (q, 2H), 3.07 (t, 4H)1 1.96 (t, 4H), 1.26 (t, 3H) ppm.

According to the analysis of related databases, 22766-68-3, the application of this compound in the production field has become more and more popular.
