With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.72551-53-2,Ethyl 1-benzylpiperidine-3-carboxylate,as a common compound, the synthetic route is as follows.
72551-53-2, Step 1: l-Benzylpiperidine-3-carbonyl chloride hydrochloride; [00273] Hydrochloric acid (20 % aq, 100 mL) was added to ethyl l-benzylpiperidine-3- carboxylate (14.2 g, 57.4 mmol) and the mixture heated at reflux for 4 h. The reaction was cooled and concentrated in vacuo to give l-benzylpiperidine-3-carboxylic acid as a pale yellow solid. This solid was dissolved in thionyl chloride and the resulting solution stirred at room temperature for 1 h. Thionyl chloride was removed in vacuo and the resulting solid was slurried in THF and azeotroped to afford the title compound as a pale yellow solid which was used without further purification (17.0 g, quant.).
72551-53-2 Ethyl 1-benzylpiperidine-3-carboxylate 2736370, apiperidines compound, is more and more widely used in various fields.
