1. Useful intermediates in the synthesis of n-1 - (s - (R *, s *) n-1 - (1,3-benzodiazepine-5-il) butil) 3,3-bis - [1 - [(4-methyl-1-chlorodiphenyl) phenyl] - 4-oxo-1 azenincarboxamida and in the continued preparation of R - (1-formula a-propil-piteronil-amine-amine, or salts not on the isomer itself). As for the scope of application, the synthetic routes of some compounds similar to the above mentioned elasticity have been described,of the azetidinocarboxamide type. But R-alpha-propyl-piperonyl-amine is a chiral amine that could therefore be a significant intermediate in the process of elastase inhibition if there were a synthetic route on an industrial scale.
