The re-emergence, in the recent years, of cyclooxygenase as a biological target in therapeutic areas other than
inflammation is likely to require new optimized leads, particularly suited for the requirements of specific drug development
programs. We developed a convenient synthesis of the known imidazole-based selective COX-2 inhibitors bearing
primary sulphonamide and methyl sulfone substituents, via Pd-catalyzed imidazoline N-arylation as a key step, followed
by dehydrogenation.
