摘要: A method for preparing 5-cyano-5H-dibenz[b,f]azepine, comprises: reacting carbamazepine of formula (II) used as dehydrating agent with bis(trichloromethyl)carbonate of formula (III) in organic solvent for 1-30 hours at 20-150°C, and obtaining 5-cyano-5H-dibenz[b,f]azepine (I) after the post-treatment of the reaction solution. The scheme is shown as below.
