Versuchsvorschrift
To 3-cyanophenyl isocyanate (1.0 g, 6.90 mmol) in THF (5 mL), ammonium hydroxide (1.7 mL, 13.8 mmol) was added. The reaction was stirred for 2 h at rt. The solvent was evaporated and the crude residue was redissolved in ethyl acetate. The organic layer was washed with water and brine and dried over sodium sulfate. The solvent was evaporated and the crude residue was purified by flash column chromatography to 41A (0.37 g).
