With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.37675-18-6,(S)-Ethyl piperidine-3-carboxylate,as a common compound, the synthetic route is as follows.,37675-18-6
[1495] LAH (118 mL, 1.0 M in Et2O, 1.0 eq.) was added to a solution of the product from Step A (18.5 g, 0.125 mmol) in THF (250 mL) at 0 C. over 20 minutes. The resulting solution was warmed slowly to room temperature and then heated at reflux 2 hours. The reaction was cooled to room temperature and quenched by the slow addition of saturated Na2SO4. The resulting slurry was dried by the addition of Na2SO4, filtered through Celite and concentrated to give a colorless oil (13.7 g, 98% crude yield). CIMS: MH+=116; [alpha]20D=-8.4 (5.0 mg in 2 mL MeOH).
The synthetic route of 37675-18-6 has been constantly updated, and we look forward to future research findings.
