Abstract:Methylation of 2-piperidone with dimethyl sulfate (DMS) in acetone at room temperature afforded N-methyl-2-piperidone in 87.6% yield with purity of 99%(GC). The structure of the product was characterized with 1H NMR. The reaction mechanism and the reaction conditions were discussed.
Key words:2-piperidone;methylation;dimethyl sulfate;N-methyl-2-piperidone
