| Use | new anticoagulant intermediate. |
| production method | acetylsalicylic acid may be used for thionyl chloride to produce acetyl salicylyl chloride, which is then condensed with ethyl acetoacetate, ethyl α-(2-acetoxybenzoyl) acetoacetate was obtained. The latter is hydrolyzed with a sodium hydroxide solution to give sodium α-(2-hydroxybenzoyl) acetoacetate, which is then cyclized under the action of sulfuric acid to give the product. |
