Procedure

To (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) (0.050 g, 0.080 mmol) and 2-fluorenone (0.0080 g, 0.044 mmol) in anhydrous acetonitrile (0.80 mL) was added Selectfluor® (0.062 g, 0.18 mmol). The reaction was stirred at room temperature overnight. Purification by flash column chromatography using 0-100% ethyl acetate/B, where B=1:1 dichloromethane/hexanes, as eluent provided the title compound as a yellow oil (0.033 g, 63%).
