Title: Novel benzodiazepine derivatives and a process for the manufacture thereof
IPC: C07D295/16
Filed: 1963-03-01
Abstract: The invention comprises compounds of the general formula <FORM:0984707/C2/1> (wherein R1 stands for a halogen atom or an alkyl, alkoxy or trifluoromethyl group, R2 and R3 each stand for an alkyl group or, together with the nitrogen atom to which they are attached, form a 5- or 6-membered heteromonocyclic group which may contain an oxygen atom or one further nitrogen atom, the broken lines radiating from the rings denote that the substituents attached thereby are optional and the broken line within the diazepine ring indicates that the double bond in the 4,5-position is optional) and acid addition and quaternary ammonium salts thereof, pharmaceutical preparations containing them, and their preparation by either reacting a benzophenone of the formula <FORM:0984707/C2/2> or a salt thereof with a strong acid, with an a  amino acid of the formula <FORM:0984707/C2/3> or an ester thereof, or a salt of this acid or ester with a strong acid, or with an a -halo-acid halide of the formula <FORM:0984707/C2/4> and treating the resulting 2-(a -halo-alkanoyl-amido)-benzophenone with ammonia or, in the case where R2 and R3 in the product are to be alkyl groups, reductively alkylating a nitro compound of the formula <FORM:0984707/C2/5> and, if desired, N1-alkylating any 1-unsubstituted cyclized compound and/or converting it or any 1-substituted cyclized compound into an acid addition or quaternary ammonium salt, the process including, if required, a reduction of any cyclized compound containing a double bond in the 4,5-position of the diazepine ring. The term "alkyl" is defined as meaning a C1-7 alkyl group.  The benzophenone starting materials are prepared by reacting a corresponding 5-halo-2-aminobenzophenone with a peracid, treating the resulting 5 - halo - 2 - nitrobenzophenone with the appropriate secondary amine, reducing the 5 - (substituted amino) - 2 - nitrobenzophenone obtained and, if desired, alkylating the reduction product.  The compounds of the invention are sedatives, muscle relaxants and anticonvulsants, and may be administered orally, parenterally or rectally in the form of pharmaceutical preparations (e.g. tablets, dragees, suppositories, capsules, solutions, emulsions or suspensions) containing them together with a carrier, with or without other (unspecified) therapeutically useful substances.  Specification 972,968 is referred to.

Abstract: 1405713 Multiphase counters INSTITUT ELEKTRONIKI I VYCHISLITELNOI TEKHNIKI AKADEMII NAUK LATVIISKOI SSR 20 Feb 1973 8314/73 Heading G4D An n-phase pulse counter comprises a first set of n gates 2-7 each having a plurality of inputs connected to the outputs of certain other gates such that the gates 2-7 form an n-stable trigger circuit 1 and a further input connected to the output of a respective one of a second set of n gates 8-13 each of which has a first input connected to the output of the preceding gate 2-7 and a second-input connected to one phase input 20-25 of the counter. In Fig. 1 the first gates 2-7 are NOR-gates while the second gates 8-13 are AND-gates. In use the six inputs are marked one at a time in succession and at each fifth pulse the trigger circuit 1 steps to its next stable state. The trigger circuit 1 passes through the sequence of six stable states in which adjacent pairs of the outputs 26-31 are marked, once for every 30 input pulses. In a second embodiment (Fig. 2, not shown) both first and second gates are NOR-gates, the trigger has seven stages and seven stable states in each of which three adjacent outputs are marked and completes a sequence every 42 input pulses. In order to form the n-stable trigger circuit each stage 2-7 has to be connected to s other stages where 3 # s # n-3. In the general case each k<SP>th</SP> second gate 8-13 has to be connected to the output of the (k+a)<SP>th</SP> first gate where a depends on the kind of gates employed. A reversible counter may be formed using a further set of n second gates connected the other way round, e.g. gate 8 input to gate 2 output and gate 8 output to gate 3 input. All second gates have three inputs, the two sets of third inputs being coupled to "up" and "down" control terminals respectively. The trigger circuit 1 can be preset to any of its states by applying a complementary input pattern to the terminals 14-19.
