molecule. To judge from one of the patents, synthesis is straightforward starting from 2-cyanobenoic acid and 2-fluorobenzoyl chloride, both commercially available. The synthetic steps are methylation of 2-cyanobenoic acid ( iodomethane ), nitrile hydrolysis with hydroxylamine , esterification with the fluoro acid chloride using DIPEA , high-temperature dehydration to the oxadiazole
