24.0 g (214 mmol) potassium-tert-butoxide in 100 mL DMF were slowly added dropwise to a solution of 13.17 g (86.0 mmol) 4-nitroanisole and 18.0 g (107 mmol) 4-chlorophenoxyacetonitrile in 50 mL DMF. The reaction mixture was stirred for 30 min at −10° C. and then poured into 300 g of a 1:1 mixture of conc. HCl and ice. After extraction with EtOAc the organic phase was washed with water, dried and concentrated to dryness by rotary evaporation in vacuo with gentle heating. The residue was treated with a 1:1 mixture of PE/EtOAc and the product that crystallised out was suction filtered. After washing with a 1:1 mixture of PE/EtOAc the crystals were dried in the air. 6.5 g of the desired product was obtained.
