EXAMPLE 13 Reduction of cyclic amine product--the reaction product of an aldehyde and ethylenediamine, for example of the formula: STR19 The imidazolidine from isobutyraldehyde and ethylenediamine (22.8 g; 0.2 mole) was heated with phosphorous acid (16.4 g; 0.2 mole) at 100°-120° for 3 hours. After cooling water and base were added. Extraction with chloroform and evaporation gave crude amine. Distillation gave 12 g of a mixture of mono and diisobutylethylenediamine, bp 160°-170°. STR20 Glc and nmr indicated the product contained approximately equal amounts of mono and dialkylated ethylenediamine.
