The mixture was stirred at room temperature for 0.5 h. Then 2-{[4-chloro-3-(trifluoromethyl)phenyl]oxy}-5-formylbenzonitrile (5.0 g, 15.35 mmol) was added. Stirring continued for 1.5 h, and the mixture was quenched by ice water. THF was removed by evaporation; the aqueous layer was extracted with DCM. The combined organic layers were washed with brine, dried over Na2SO4, filtered and concentrated to afford the title compound (1.8 g, 5.56 mmol, 36.2% yield).
