Reaction Steps

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) (0.40 g, 0.64 mmol) in acetone (30 mL) was added saturated aqueous sodium bicarbonate (3 mL). The reaction was heated to reflux for 12 hours, cooled, and concentrated. The reaction mixture was partitioned between ethyl acetate and water. The organic layer was dried and concentrated. Purification by flash column chromatography using 100-40% A/B, where A=1:1 dichloromethane/hexanes and B=3:1 ethyl acetate/acetone, as eluent provided the title compound as a white solid (0.095 g, 19%).
