Process for the preparation of novel benzylamines

摘要

The preparation of novel benzylamines of the formula I <IMAGE> in which the symbols R1 to R5 have the meanings stated in Claim 1, as well as their physiologically tolerated acid addition salts with inorganic or organic acids is described. The compounds of the formula I have valuable pharmacological properties, especially an antiulcer effect, a secretolytic, cough-suppressant effect and an effect enhancing the production of the surfactant or antiatelectasis factor in the alveoli. The compounds of the formula I are prepared by introducing the radical R5 into an appropriate compound in which R5 is hydrogen.
