Downstream synthetic route of 22766-68-3

As the paragraph descriping shows that 22766-68-3 is playing an increasingly important role.

22766-68-3, Ethyl quinuclidine-4-carboxylate is a quinuclidine compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

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.

As the paragraph descriping shows that 22766-68-3 is playing an increasingly important role.
