ethyl N-chlorocarbamate

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: The mixture of 150 ml of methanol, 25 g of m-fluoroaniline, 30 g of triethylamine and 32.5 g of ethyl chlorocarbamate was heated under reflux condition. After the completion of the reaction, the solvent was evaporated under reduced pressure to obtain the residue, to which was added 100 ml of water and 100 ml of benzene. The benzene layer was separated, washed twice with water and dried over anhydrous sodium sulfate. The solvent was evaporated to obtain the residue, which was distilled under reduced pressure, and there was obtained 12.5 g (yield 34.8%) of ethyl m-fluorophenylcarbamate as colourless oil having a boiling point of 102° C/1.5 mmHg. was heated under reflux condition After the completion of the reaction the solvent was evaporated under reduced pressure to obtain the residue The benzene layer was separated washed twice with water dried over anhydrous sodium sulfate The solvent was evaporated to obtain the residue, which was distilled under reduced pressure
