• Verwenden

  Fluanisone is a neuroleptic with sedative properties and relatively poorly expressed antipsychotic action. It is used as an independent or adjuvant drug for psychomotor excitement in severe and chronic schizophrenia and for manic-depressive disorder.

• Verwenden

  Fluanisone is a butyrophenone derivative with sedative properties. It is a typical antipsychotic and is used in the treatment of schizophrenia.

• Definition

  ChEBI: Fluanisone is an aromatic ketone.

• Manufacturing Process

  To a suspension of 341 parts of aluminum chloride in 1740 parts of carbon disulfide are added 96 parts of fluorobenzene with stirring and cooling. While the temperature is maintained at about 10°C, 141 parts of γ-chlorobutyryl chloride are added. After the addition is completed, the cooling bath is removed and the stirring is continued for 2 hours. The reaction mixture is poured into ice water. The organic layer is separated, washed with water, dried over anhydrous sodium sulfate, and filtered. The filtrate is concentrated under reduced pressure, and the residue is distilled to yield γ-chloro-p-fluorobutyrophenone boiling at about 136°-142°C/6 mm
  A mixture of 6.6 parts of γ-chloro-p-fluoro-butyrophenone and 12.5 parts of 1- (o-anisyl)piperazine is heated for 10 hours at a temperature of 110°C. The reaction mixture is treated with 800 parts of ether and filtered. The ether layer is washed with water, dried over anhydrous potassium carbonate and filtered, whereupon hydrogen chloride gas is introduced into the solution. The precipitate is collected on a filter and dissolved in a mixture of 240 parts of 2- propanol and 80 parts of acetone to yield 1-[γ-(p-fluorobenzoyl)propyl]-4-(o-anisyl)piperazine hydrochloride. This monohydrochloride is collected on a filter and dissolved in 240 parts of 2-propanol. Anhydrous, gaseous hydrogen chloride is passed through the solution. On cooling, the 1-[γ-(p-fluorobenzoyl) propyl]-4-(o-anisyl)piperazine dihydrochloride precipitates.
  A second crop of product is obtained by passing hydrogen chloride gas through the solution of mother liquors. The pale-brown, amorphous powder is collected on a filter and found to melt at about 205°-205.5°C.
  This salt is dissolved in water and treated with sodium hydroxide. The precipitated base is recovered by filtration and recrystallized from diisopropyl ether. The white crystals melt at about 67.5°-68.5°C.

• Therapeutic Function

  Neuroleptic

• Synthese

  Fluanisone, 4??-fluoro-4-[4-(o-methoxyphenyl)-1-piperazinyl]-butyrophenone (6.3.12), is synthesized by reacting 1-(2??-methoxyphenyl)-piperazine with 4
  -chloro- 4??-fluorobutyrophenone (6.3.4) [50].
