Nordazepam Usage And Synthesis
Chemical PropertiesOff-White Solid
OriginatorMadar,Ravizza, Italy ,1973
UsesThe primary metabolite of diazepam. A ligand for the GABAA receptor benzodiazepine modulatory site. This is a controlled drug precursor therefore a liscence may be required for purchase
UsesThe primary metabolite of Diazepam. A ligand for the GABAA receptor benzodiazepine modulatory site. Anxiolytic. Controlled substance (depressant).
DefinitionChEBI: A 1,4-benzodiazepinone having phenyl and chloro substituents at positions 5 and 7 respectively; it has anticonvulsant, anxiolytic, muscle relaxant and sedative properties but is used primarily in the treatment of anxiety.
Manufacturing ProcessA solution of 3.1 g of (2-benzoyl-4-chlorophenyl-carbamoylmethyl)carbamic acid benzyl ester in 30 cc of 20% hydrobromic acid in glacial acetic acid was stirred for 45 minutes at room temperature. On addition of 175 cc of anhydrous ether, a gummy solid precipitated. After several minutes the ether solution was decanted. The resultant 5-chloro-2-glycylaminobenzophenone was not isolated, but about 155 cc of ether was added to the residue and after chilling in an ice bath, 10% sodium hydroxide was added until the mixture was alkaline. The ether layer was then separated, washed twice with water and dried over sodium sulfate. After filtration, the ether solution was concentrated to dryness in vacuo. The residue was crystallized from benzene to yield 7-chloro-5-phenyl-3H-1,4-benzodiazepin-2(1H)-one.
Therapeutic FunctionTranquilizer
