Procedure

To 2-(4-(1-(4-(trifluoromethoxy)phenyl)-1H-1,2,4-triazol-3-yl)phenyl)cyclohexanamine (CB56) (0.200 g, 0.497 mmol) and (Z)-4-nitrophenyl (3-(2-isopropyl-5-methylphenyl)-4-oxothiazolidin-2-ylidene)carbamate (CA50) (0.205 g, 0.497 mmol) were dissolved in acetonitrile (10 mL) in a vial. Cesium carbonate (0.162 g, 0.497 mmol) was added, and the reaction was stirred at room temperature for 25 hours. The solution was adsorbed onto silica. Purification by reverse-phase flash column chromatography using 0-100% acetonitrile/water as eluent afforded the title compound as a red oil (0.020 g, 6%).
