Participants

Reaction Steps

Using the method of Birch and Dastur, Austral. J. Chem., 26, 1364 (1973), a solution of 48 g of p-tolualdehyde in 185 ml of benzene was added dropwise to a stirred solution of 25 g of sym-dimethylethylenediamine in 95 ml of benzene, and heated at 60° for 2 hrs. Evaporation and distillation at 52° (0.1 mm) afforded 48 g, identified by nmr.
