Synthesis
Clonixin synthesis: M. H. Sherlock, N. Sperber, BE 679271; eidem, U.S. Patent 3,337,570 (1966, 1967 both to Schering).

Clonixeril

The glyceryl ester of clonixin, clonixeril, is also a NSAID. It was prepared by a somewhat roundabout method.

Clonixeril synthesis:[2][3]

Clonixin was reacted with chloroacetonitrile and triethylamine to give 2. Heating with potassium carbonate and glycerol actonide displaced the activating group to produce ester 3, which was deblocked in acetic acid to produce clonixeril (4).
