Procedure

3-Cyano-4-fluoronitrobenzene (3.3 g, 19.9 mmol) was dissolved in ethyl acetate (10 mL). Morpholine (2.2 mL, 25 mmol), and N,N-diisopropylethylamine (3.5 mL, 20 mmol) were added and the mixture stirred overnight at room temperature. At 17 h, additional ethyl acetate (150 mL) was added and the combined mixture was washed with water (50 mL) and brine (50 mL), dried (Na2SO4), filtered and concentrated under vacuum. The residue was used without further purification.
