Versuchsvorschrift
10 g of magnesium sulfate was added to a stirred solution of 13.8 g of propargylamine and 26.5 g of benzaldehyde in 75 ml of benzene and the resulting mixture was stirred at room temperature for 30 minutes. The mixture then was filtered and water was removed from the filtrate by azeotropic distillation. Then the remaining benzene was evaporated and the residue was distilled to give N-benzylidene-2-propyn-1-amine (1A) b.p.: 64°-66° C. (0.2 Torr.).
