With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.24666-55-5,Benzyl (2,6-dioxopiperidin-3-yl)carbamate,as a common compound, the synthetic route is as follows.
3-N-benzyloxycarbonylamino-2,6-piperidinone hydrochloride 40 g (0.153 mol) was added to a 1 L reaction flask.40% hydrobromic acid solution 300ml, acetic acid 400ml,Stir well and mix well, heat to 60 C, keep warm for 1 h,Cool to room temperature, distill off the solvent and water under reduced pressure.Add 1 L of ethyl acetate to the residue and stir for 0.5 h.The product was white filtered to give a white solid (30.4 g, yield: 95.2%)., 24666-55-5
The synthetic route of 24666-55-5 has been constantly updated, and we look forward to future research findings.
