Versuchsvorschrift
2,6-Difluoro-4-methoxy-benzonitrile (Mol. Cryst. Liq. Cryst. 1989, 172) (200 mg, 1.18 mmol) was dissolved in ethanolic ammonia (2M solution, 10 ml) and the mixture was heated at 140° C. in an autoclave for 16 hours. The reaction mixture was cooled to room temperature and the solvent was evaporated under reduced pressure. The residue was purified by chromatography on silica gel using ethyl acetate in pentane as eluant (20:80) to give the title compound as a white solid (165 mg). LRMS: m/z (ES+) 189 [MNa+]
