Cimicoxib (UR-8880 trade name Cimalgex) is a non-steroidal anti-inflammatory drug (NSAID) used in veterinary medicine to treat dogs for pain and inflammation associated with osteoarthritis and for the management of pain and inflammation associated with surgery.[1] It acts as a COX-2 inhibitor.

Cimicoxib synthesis:[2]

Reaction of the imine with tosylisocyanate in the presence of potassium carbonate leads to what may be viewed as 2+3 cycloaddition of the nitrogen analogue of a ketene to form the imidazole ring.
