Uses

4-Hydroxythiobenzamide is used in the synthesis of PPARα agonists used in increasing HDLc levels. Also used in the synthesis of potent CDK5 inhibitors in the treatment of Alzheimer’s disease.

Synthesis

4-Hydroxythiobenzamide is an important intermediate of Febuxostat, a new anti-gout drug. A patent discloses a method for preparing p-hydroxythiobenzamide. Specifically, a certain amount of water, p-cyanophenol, sodium hydrosulfide, and secondary amine are mixed evenly. At a specific temperature, an organic weak acid is added dropwise. After the reaction is completed, the mixture is filtered, and the filter cake is dried to obtain 4-Hydroxythiobenzamide.
