Pranoprofen Usage And Synthesis
- Chemical PropertiesOff-White Solid
- OriginatorNiflan, Yoshitomi ,Japan ,1981
- UsesPranoprofen is an anti-inflammatory used in ophthalmology.
- Manufacturing ProcessA mixture of 100 g of ethyl 2-cyano-2-(5H-[1]benzopyrano[2,3-b]-pyridin-7yl)propionate, 500 ml of glacial acetic acid and 200 g of concentrated hydrochloric acid is refluxed for 48 hours. The reaction mixture is concentrated, and the residue is dissolved in hot water. The solution is adjusted to pH 2 to 3 by addition of 10% sodium hydroxide. The resulting crystalline precipitate is washed thoroughly with water, and recrystallized from aqueous dioxane to give 74 g of 2-(5H-[1]benzopyrano[2,3-b]-pyridin-7yl)propionic acid as white crystals melting at 183°C to 183.5°C.
- Therapeutic FunctionAnalgesic, Antiinflammatory
