With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.1454-53-1,Ethyl 1-benzyl-4-oxopiperidine-3-carboxylate hydrochloride,as a common compound, the synthetic route is as follows.
Step A:l-Benzyl-3-ethoxycarbonyl-4-piperidone hydrochloride (12.89 g, 43.3 mmol) was suspended in a sodium methoxide solution in methanol (25 % wt/wt, 50 mL, 216. 2 mmol) and formamidine acetate (5.4 g, 51.9 mmol) was added to the mixture. The reaction mixture was refluxed until all of the starting material was consumed (2 h). The methanol was removed under reduced pressure, and the resulting white solid was dissolved in a 3/1 mixture of chloroform / isopropanol. The mixture was washed with water and brine, dried over Na2S04, filtered and evaporated to give the desired product as a white solid (9.4 g). MS (ESEI): 242.1 [M+l]+, 1454-53-1
The synthetic route of 1454-53-1 has been constantly updated, and we look forward to future research findings.
