Procedure

4-Fluorobenzonitrile (0.847 g, 7 mmol), 1H-[1,2,3]triazole (0.483 g, 7 mmol), Cs2CO3 (2.27 g, 7 mmol) and DMF (8 ml) and a magnetic stirrer were placed in a vial. The mixture was heated with stirring for 3 h at 80° C. Extractive work-up (EtOAc/H2O) and subsequent drying (Na2SO4) gave a crude product which was purified on silica giving 0.55 g (46%) of the title intermediate.
