A flask was charged with tert-butyl 2-(3-cyano-4-fluorophenyl)propanoate (0.07 g), N-(4-chlorophenethyl)-4-hydroxybenzamide (0.105 g), and potassium carbonate (0.047 g) in 1 ml of DMSO and stirred at 95° C. for one day. The reaction was taken up in dichloromethane and washed with water. The organic layer was collected, dried over MgSO4, filtered, and concentrated. The crude material was purified by silica gel chromatography, eluting with a solvent system of 5%-80% ethyl acetate/hexanes gave tert-butyl 2-(4-(4-((2,4-dichlorophenethyl)carbamoyl)phenoxy)-3-cyanophenyl)propanoate (0.102 g).
