The convenient and simple method for the synthesis of 2-(bromomethyl)aziridines was developed. The condensation of aromatic aldehydes and allylamine gave the N-aryllithene-2- propenylamines 6a-c and the subsequent bromination of N-aryllidene-2-propenylamines 6a-c afforded N-(arylidene)-2,3-dibromopropylamines 7a-c. Finally, The reductive and intramolecular cyclization reaction of N-(arylidene)-2,3-dibromopropylamines 7a-c by treatment with sodium borohydride obtained the 2-(bromomethyl)aziridines in high yield.
