Abstract:OBJECTIVE To investigate a practical and convenient process for the synthesis of N-ethyl-N-methylcarbamoyl chloride.METHODS N-methylethylamine was synthesized from benzaldehyde and ethylamine aqueous solution.The key steps included methylation of N-benzylideneethylamine by dimethyl sulfate,followed by hydrolyzation and neutralization with sodium hydroxide.N-methylethylamine then was reacted with triPhogene to afford the N-ethyl-N-methylcarbamoyl chloride.RESULTS The chemical structure of target compound was determined by 1HNMR.The overall yield was 57.1%.CONCLUSION This Process,as compared to reported methods,has the advantages of milder reaction condition,simpler process and higher yield.
Keywords:Rivastigmine hydrogentartrate  Cholinesterase inhibitor  N-methylethylamine  N-ethyl-N-methylcarbamoyl chloride  Synthesis
