Reaction Steps
n-Butyllithium (2.5 mmol) was slowly added to a solution of 3-(2,6-dichlorophenyl)-5-(3,4,5-trichlorothien-2-yl)-1-methyl[1,2,4]triazole (325 mg, 1.0 mmol) in THF at -78° C., and the mixture was stirred one hour. Bromine (3.0 mmol) was added and the reaction stirred two hours, then diluted with water, extracted with ether, washed with brine, and dried over magnesium sulfate. The product was concentrated to 620 mg of dark oil. This was chromatographed (SiO2, 10% EtOAc-Hex) to give 79 mg of the title product as a pink solid. MP 197-199° C.
