Reaction Steps

Compounds of this invention with Formulae I-IX may be prepared as illustrated by the exemplary reaction in Scheme 2. Reaction of 3-bromo-furan-2-carboxylic acid with thionyl chloride produces intermediate, 3-bromo-furan-2-carbonyl chloride, followed by refluxing with 4-trifluoromethyl-benzamidoxime in pyridine produces the product 5-(3-bromo-furan)-3-(4-trifluoromethyl-phenyl)-[1,2,4]-oxadiazole.
