As a common heterocyclic compound, it belongs to quinuclidine compound, name is Ethyl quinuclidine-4-carboxylate, and cas is 22766-68-3, its synthesis route is as follows.
Example 32 Preparation of 1-butyl-4-[hydroxy(di-3-thienyl)methyl]-1-azoniabicyclo[2.2.2]octane bromide A solution of n-Butyl lithium (2.5M in hexanes, 5.0 mL, 12.5 mmol) was chilled to -78 C. under Ar. 3-Bromothiophene (1.15 mL, 12.3 mmol) dissolved in ethyl ether (4.0 mL) was slowly added to the reaction mixture. The reaction was stirred for 30 min and then ethyl 1-azabicyclo[2.2.2]octane-4-carboxylate (0.7640 g, 4.16 mmol) in THF/Et2O (4 mL/4 mL) was added. The reaction was allowed to warm up from -78 C. to room temperature over 16 h then slowly quenched with water. The reaction was concentrated and the resulting brown solid was taken up in water and DCM. The organic phase was separated, dried over MgSO4, filtered and concentrated under vacuum to give a brown solid. The solid was dissolved in DMSO and purified by preparatory HPLC to give the title compound (0.1736 g, 9.4%). EI-MS m/z 362(M+) Rt (1.73 min).
With the complex challenges of chemical substances, we look forward to future research findings about Ethyl quinuclidine-4-carboxylate
