Procedure

Using the method of Birch and Dastur, Austral. J. Chem., 26, 1364 (1973), a solution of 5.5 g of benzaldehyde in 25 ml of benzene was added dropwise to a stirred solution of sym-dimethylethylenediamine in 15 ml of benzene, and heated at 60° for 2 hrs. Evaporation and distillation at 55° (0.35 mm) afforded 6.4 g, identified by nmr.
