Clidanac Chemical Properties,Uses,Production
Uses
Clidanac can be used as a replacement for retinol for skin treatment, to treat anal fissures, and as a preparation of ester prodrugs of NSAIDs.
Trade name
Britai (Bristol Banyu, Japan), Indanal (Takeda, Japan).
Clinical Use
Clidenac is used for the relief of pain and in- flammation related to arthrosis deformans, periarthritis humeroscapularis, cervical syndrome, and lumbago.
Synthesis
Synthesis: formylation of cyclohexylbenzene using dichloromethyl methyl
ether and titanium tetrachloride gives 4-
cyclohexylbenzaldehyde, which is condensed
with diethyl malonate to yield diethyl 4-
cyclohexylbenzylidenemalonate. Treatment
of the latter with potassium cyanide in
ethanol at 70 ?C gives ethyl 3-cyano-3-(4-
cyclohexylphenyl)propionate, which is converted to 4-cyclohexylphenylsuccinic anhydride following acid hydrolysis and treatment with refluxing acetic anhydride. An intramolecular Friedel – Crafts acylation (aluminum chloride – methylene chloride) affords
5-cyclohexyl-3-oxo-1-indanecarboxylic acid,
which is catalytically reduced using 10 % palladium on charcoal in the presence of perchloric
acid to give 5-cyclohexyl-1-indanecarboxylic
acid. Chlorination using N-chlorosuccinimide
in N,N-dimethylformamide (DMF) gives clidenac.
