摘要

Tepoxalin (6) l is a potent inhibitor of both the cyclooxygenase and lipoxygenase pathways of the arachidonic acid cascade. We have previously described a highly efficient regioselective synthesis of this compound. 2 Due to toxicity considerations it became desirable to synthesize tepoxalin without using methylene chloride or oxalyl chloride in the last step. Herein we report a high-yield synthesis of tepoxalin which meets this objective.
