| titleOfInvention | PROCEDURE FOR OBTAINING NEW DERIVATIVES OF A- 4, AMINOBUTYRIC ACID. |
| abstract | Procedure for obtaining new derivatives of 4-aminobutyric acid, of the general formula: R1CONHCH2CH2CH2CONR2R3 where it represents an alkyl or aryl radical; R3 and R3, which may be the same or different, each represent a hydrogen atom or a hydrocarbon radical of 1 to 8 carbon atoms or together with the nitrogen atom may constitute a pyrrolidine, morpholine, piperidine, mono or disubstituted hydantoin in the 5-position, or mono or disubstituted barbituric acid in the 5-position, characterized by comprising the reaction of a compound of general formula R2R3NA where R2 and R3 have the meanings described above and A represents a hydrogen or an ion alkaline, with an activated derivative of 4-aminobutyric acid represented by the general formula: **(See formula)** where R1 has the aforementioned meaning, W represents a chlorine or bromine atom, a dichlorophosphoric radical, an alkyloxycarbonyloxy radical with an alkyl radical of 2 to 5 carbon atoms, a branched aliphatic acyloxy radical, an alkyl- or arylsulfonyloxy radical, a dimethylformiminio-sulfonyloxy radical or a 0-dialkyl-isoureido radical, and X represents a hydrogen or, taken together, X and W represent a bond between nitrogen and carbonyl of the butyryl moiety.
