Procedure

A solution of 4-chloro-3-nitrobenzonitrile (5 g) in THF (200 mL) at room temperature was treated with K2CO3 (19 g), followed by 2,5-difluorophenol (3.7 g). After stirring at room temperature for 18 hrs, the solid was filtered off and rinsed with copious amounts of EtOAc. The filtrate was washed sequentially with saturated aqueous NaHCO3 solution, water, and saturated aqueous NaCl solution, dried over anhydrous Na2SO4, filtered, and concentrated in mow. The residual was triturated with hexanes and collected by suction to furnish the desired product 21, which was used directly in the next step without further purification.
