Versuchsvorschrift

To a solution of 2-fluoro nitrobenzene (1.41 g, 10 mmol, 1.0 equiv) and 3-hydroxybenzonitrile (1.19 g, 1.0 equiv) in 10 mL of DMF was added K2CO3 (2.76 g, 2 equiv). After stirring at 60° C. for 3 h, the mixture was diluted with EtOAc and washed with H2O. The organic layer was dried over MgSO4, filtered and evaporated to give 3-(2-nitrophenoxy)benzonitrile (2.38 g, 99%). MS found for C13H9N2O3 (M+H)+: 241.
