Abstract: The invention comprises: (a) 10, 11-dihydro-11-oxo-5H-dibenzo-[b, e] [1, 4]-diazepine derivatives of the general formula: <FORM:0961106/C1/1> (wherein R1 represents a hydrogen atom or a methyl or ethyl group, X represents a normal or branched hydrocarbon chain of 2 or 3 carbon atoms, Y represents a C2- 4 dialkylamino group, a 5- or 6-membered N-heterocyclic group (not necessarily connected through the nitrogen atom), or a 6-membered N-heterocyclic group in which one -CH2- group is replaced by -O-, -NH-, -N(CH3)- or -N(C2H5)-, and R2 and R3 represent hydrogen or chlorine atoms or methyl, ethyl, methoxy, ethoxy, methylmercapto or ethylmercapto groups) and their non-toxic therapeutically useful acid addition salts and quaternary ammonium derivatives, and the preparation thereof by reaction of a compound of the general formula: <FORM:0961106/C1/2> or a metal derivative thereof with a tertiary aminoalkanol ester Z-X-Y (wherein Z represents an acid radical) or a corresponding quaternary ammonium derivative, or with a compound Z-X-Halogen followed by reaction of the product with a secondary amine H-Y or a corresponding tertiary derivative, or with an alkylene oxide followed by esterification with a hydrohalic acid and reaction of the product with H-Y or a corresponding tertiary amine, and in each case, if desired, converting the product into a quaternary ammonium derivative if it is not already in this form, and/or, if desired, when R1 in the product is hydrogen, treating it with a reactive methyl or ethyl derivative, preferably after previous metallization; (b) 10-g -dimethylaminopropyl-, 10-b -dimethylaminoethyl-, 10-b -piperidinoethyl-, 10-g -piperidinopropyl-, 10-b -morpholinoethyl- and 10-g -morpholinopropyl-5, 11-dimethyl-10, 11-dihydro-5H-dibenzo-(b, e] [1, 4]-diazepine, and the preparation of these and other compounds of the general formula: <FORM:0961106/C1/3> (wherein X represents a normal or branched hydrocarbon chain of 2 or 3 carbon atoms, Y represents a C2- 4 dialkylamino group, a pyrrolidin or piperidino group or one of the last two groups in which one -CH2- group is replaced by -O-, -NH-, -N(CH3)- or -N(C2H5)-, R1 and R2 represent, interchangeably, hydrogen atoms or methyl or ethyl groups, and R3 and R4 represent, interchangeably, hydrogen or chlorine atoms or methyl, ethyl, methoxy or ethoxy groups) and their non-toxic therapeutically useful acid addition and C1- 3 alkyl quaternary ammonium salts, by processes analogous to those set out in (a); and (c) the preparation, by analogous processes, of the compounds of Specifications 959,994 and 959,995, with the further possibility, in the case of the compounds of Specification 959,994, of acylating or benzylating a 10-unsubstituted product so as to introduce a formyl, acetyl, benzoyl or benzyl group in the 10-position.  Pharmaceutical preparations, useful as antihistaminics, analgesics, spasmolytics, anti-Parkinson agents, tranquillizers, psychic energizers, thymoleptics and psycho stimulants, comprise the compounds of the invention or the compounds obtainable by the processes of the invention, composited with a pharmaceutical carrier to provide solutions, syrups, sprays, tablets, capsules, suppositories or powders.  Specification 961,105 also is referred to.
