| titleOfInvention | Synthesis method of intermediate N-phenyl-4-piperidone |
| abstract | The invention discloses a synthetic method of an intermediate N-phenyl-4-piperidone, which comprises the following steps: dissolving aniline in ether, adding a catalyst, adding 3-methyl-1, 3, 5-pentanetriol under stirring, heating for reflux reaction, filtering after the reaction is finished, and distilling under reduced pressure to obtain N-phenyl-4-methyl-4-piperidinol; then, demethylation and oxidation reaction are carried out to prepare the N-phenyl-4-piperidone. The synthesis method has the advantages of simple preparation process operation, short production process, high raw material conversion rate, low production cost and high economic benefit. |
