As a common heterocyclic compound, it belong quinuclidine compound,Ethyl quinuclidine-4-carboxylate,22766-68-3,Molecular formula: C10H17NO2,mainly used in chemical industry, its synthesis route is as follows.
In a 500 mL three-necked flask, phenyllithium (160 mL, lM in THF) was treated with nitrogen Was slowly added dropwise to a solution of compound 1-4 (6.8 g, 0.04momicron1) in tetrahydrofuran (120 mL) Control the temperature at -50 C and stir at room temperature overnight. Water (200 mL) was added to quench the reaction, Extracted with ethyl acetate (500 mL), the organic layer was washed with saturated brine, dried over sodium sulfate, The solvent was evaporated under reduced pressure to give 6.8 g of a brown viscous solid, Ethyl acetate: petroleum ether = 1: 2 (200 mL) was added and stirred at room temperature for 2 h, filtered, The filter cake was washed with petroleum ether and dried to give a 5.1g lime light gray solid.
With the synthetic route has been constantly updated, we look forward to future research findings about Ethyl quinuclidine-4-carboxylate,belong quinuclidine compound
