Procedure

To a dry 2 dram vial equipped with magnetic stirrer was added (Z)-1-(3-(2-isopropyl-5-methylphenyl)-4-oxothiazolidin-2-ylidene)-3-(4-(1-(4-(trifluoromethoxy)phenyl)-1H-1,2,4-triazol-3-yl)phenethyl)urea (F5) (0.20 g, 0.32 mmol) and anhydrous dichloromethane (0.5 mL). To this solution was added bromine (0.033 mL, 0.64 mmol). The reaction was stirred overnight at room temperature. Purification by flash column chromatography using 0-100% ethyl acetate/hexanes as eluent provided the title compound as a clear colorless oil (0.041 g, 18%).
