Fenbufen is a nonsteroidal anti-inflammatory drug used to treat pain.[1]

Fenbufen is a member of the propionic acid derivatives class of drugs.[2]

It was introduced by American Cyanamid under the trade name Lederfen in the 1980s. Due to liver toxicity, it was withdrawn from markets in the developed world in 2010.[3][4]: 370, 383–384 

As of 2015 it was available in Taiwan and Thailand under several brand names.[5]

Preparation

Fenbufen can be synthesized by acylation of biphenyl with succinic anhydride under Friedel-Crafts conditions.[6]
