Versuchsvorschrift

A mixture of aminobenzene (0.931 g, 10 mmol) and acetone cyanohydrin (2 ml) was heated to reflux and stirred for 20 h. After being cold to room temperature, the reaction mixture was poured into ethyl acetate (40 ml) and washed with cold water (2×30 ml). The organic layer was dried over MgSO4, concentrated under vacuum to dryness to yield 2-methyl-2-phenylaminopropanenitrile, 6a (1.51g, 9.4 mmol, 94%) as slurry brown liquid.
