Suxibuzone is an analgesic used for joint and muscular pain. It is a prodrug of the non-steroidal anti-inflammatory drug (NSAID) phenylbutazone,{{Cite journal|vauthors=Yasuda Y, Shindo T, Mitani N, Ishida N, Oono F, Kageyama T|date=1982|title=Comparison of the absorption, excretion, and metabolism of suxibuzone and phenylbutazone in humans|journal=Journal of Pharmaceutical Sciences|volume=71|issue=5|pages=565–72|pmid=7097505|doi=10.1002/jps.2600710521}} and is commonly used in horses.{{Cite journal|vauthors=Sabaté D, Homedes J, Salichs M, Sust M, Monreal L|date=2009|title=Multicentre, controlled, randomised and blinded field study comparing efficacy of suxibuzone and phenylbutazone in lame horses|journal=Equine Veterinary Journal|volume=41|issue=7|pages=700–5|pmid=19927590|doi=10.2746/042516409X464807}}

Synthesis

Suxibuzone is synthesized by the following method:Esteve, J. et al, Quim. Ind. (Madrid), 1971,17, 107. Patent:Esteve Dr Antonio, DE1936747A1 (1970 to Laboratorios Del Dr. Esteve S.A., Barcelona (Spanien)). (Precursor:Dhareshwar, Sundeep S.; Stella, Valentino J. (2010).

Phenylbutazone [50-33-9] (1) is hydroxymethylated with formaldehyde giving ~86% 4-butyl-4-(hydroxymethyl)-1,2-diphenylpyrazolidine-3,5-dione [23111-33-3] (2). This is then esterified with succinic anhydride. [108-30-5] (3) to give (4).
