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 40117-63-3,Quinuclidine-4-carboxylic acid hydrochloride, as follows.40117-63-3
Step 1. Quinuclidin-4-ylmethanol Quinuclidine-4-carboxylic acid hydrochloride (6.0 g, 0.03 1 mmoles) in tetrahydrofuran (300 ml) was treated with lithium aluminum hydride (5.0 g, 0.137 mmoles) at ambient temperature for 18 hours. Water (20 ml) and 10% aqueous sodium hydroxide (7.5 ml) was added carefully and the mixture filtered, washing with diethyl ether. The combined filtrates were evaporated to dryness to give the title compound as a white solid 4.04 g, (91%): MS (+ve ion electrospray) m/z 142 (MH+, 100%)
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. 40117-63-3, We look forward to the emergence of more reaction modes in the future.
