摘要
Intramolecular halocyclization of N-allyl-4,5-dihydro-3H-1-benzazepin-2-amines, obtained by consecutive methylation and allylamination of benzazepin-2-ones, by the action of N-iodo(bromo)succinimide in acetonitrile at room temperature lead to the formation 1-(iodo(bromo)methyl)-2,4,5,6-tetrahydro-1H-imidazo[1,2-a][1]benzazepines in high yields.
