Abstract

5-Alkyl-10-amino-10,11-dihydrodibenzo[b,f]azepines, useful as starting materials for the preparation of agricultural fungicides and also as therapeutic agents, are obtained by the reaction in an inert organic solvent of an N-alkyl-N-o-tolylanthranilonitrile with an alkali metal amide prepared from an amine, and the imino radical in the resulting 10-imino-10,11-dihydrodibenzo[b,f]azepine is converted to the amino radical by catalytic hydrogenation.
