With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.10315-06-7,Methyl 1-benzylpiperidine-4-carboxylate,as a common compound, the synthetic route is as follows.
Dried to 30L jacketed reactor was slowly purged with nitrogen, the 1.87kg1-benzyl-4-piperidine carboxylic acid methyl ester (8mol) and 2.0kg of toluene into a reactor, with stirring, cooled to an internal temperature of -5 . The resulting red aluminum – morpholine complex (approximately 8.8mol) was dropped to control the reaction temperature at 0 , 1 mixture liquid is completed, 0 reaction was continued for 30min. Was added slowly prepared 4N sodium hydroxide solution (containing 1.1kgNaOH), control the internal temperature not higher than 20 , the addition was completed, stirring was stopped, the organic layer was washed with water (11.0kg / times, 4 times), organic layer was concentrated under reduced pressure at 75 deg.] C and concentrated until no solvent was distilled off to give 1-benzyl-4-piperidine carbaldehyde 1.57kg, as a pale yellow oily liquid. Yield: 96.5%. HPLC: 99.03%
10315-06-7, The synthetic route of 10315-06-7 has been constantly updated, and we look forward to future research findings.
