Versuchsvorschrift
Propargyl p-toluenesulphonate (6.0 g, 0.05 mole) was heated with 2,6-dimethylaniline (6.0 g, 0.05 mole) on steam bath for 2 hours, poured into water (100 ml), extracted into methylenedichloride (50 ml), dried (MgSO4), filtered, solvent evaporated and the product distilled to give 2,6-dimethylphenyl propargylamine, identical with that in Route II. Subsequent preparative steps were as outlined in Route II.
