Synthesis and properties of new functionalized 2-benzazepines

2-Aryl-4-hydroxy-2,3-dihydro-1H-2-benzazepine-5-carbonitriles were obtained by the cyclization of methyl esters of N-aryl-N-(2-cyanomethylbenzyl)aminoacetic acids by the action of sodium methylate. The keto—enol tautomerism of these compounds and their reactions with hydrazines were studied.
