5382-23-0 - Reference Information
| use | pharmaceutical intermediates. |
| production method | methylamine is used as raw material, and is obtained by addition, cyclization, hydrolysis elimination, catalytic hydrogenation and chlorination. 1. The addition of methylamine reacts with methyl acrylate to obtain N-methyl-N-,N-bis (β-methoxycarbonyl ethyl) amine (adduct). 2. The cyclization reacts N-methyl-N,N-bis (β-methoxycarbonyl ethyl) amine (adduct) with sodium methoxide to form 1-methyl-3-methoxycarbonyl Piperidone-[4]. 3. Hydrolysis and elimination will produce 1-methyl -3-methoxycarbonyl piperidone-[4] reacts with concentrated hydrochloric acid to obtain 1-methyl -4-piperidone hydrochloride. 4. Catalytic hydrogenation Hydrogenates the above hydrochloride at room temperature. 5. The hydrogenation product is reacted with thionyl chloride to obtain 4-chloro-1-methylpiperidine. |
