Benorilate
Chemical compound
From Wikipedia, the free encyclopedia
Benorilate (INN), or benorylate, is an ester-linked codrug of aspirin with paracetamol. It is used as an anti-inflammatory and antipyretic medication. In the treatment of childhood fever, it has been shown to be inferior to paracetamol and aspirin taken separately. In addition, because it is converted to aspirin, benorylate is not recommended in children due to concerns about Reye syndrome.[1]

Synthesis
Acetylsalicoyl chloride (1) condenses with paracetamol (2) to give benorilate (3).[2][3][4][5]

Alkaline hydrolysis of the acetyl ester moiety of benorilate yields another pharmaceutical, acetaminosalol (phenetsal).[6]
