Abstract
Procedure for the preparation of new 1.5 benzodiazocins of the general formula **(See formula)** wherein R1 represents hydrogen or a low molecular weight, optionally substituted, straight or branched alcohol, alkenyl, alkynyl or cycloalkoxy radical; R2 signifies a halogen atom, a hydroxy group or an acyloxy group, and phenyl radicals A and B are optionally substituted with one or more substituents, namely nitro, trifluoromethyl, halogen, alcohol, alkoxy or thiomethyl, or in which possibly two contiguous carbon atoms of the phenyl radicals are linked through an alcoholenedioxy group; as well as its acid addition salts, characterized in that an acyldiamine of the general formula is cyclized **(See formula)** in which R1, A and B have the aforementioned meanings and R means a hydroxy or acyloxy group, at elevated temperature, optionally in an inert solvent with phosphorous oxyhalides, preferably phosphorous oxychloride, if desired an acyloxy group is transformed into the hydroxy group and eventually the compounds of formula I obtained are transformed into their salts by the addition of acid.
