Reaction Steps

2-(t-Butylamino)ethylchloride hydrochloride (1.2 g, 7.0 mmol) is dissolved in aqueous dimethylamine solution (40% by weight, 22 mL) in a sealed tube. The mixture is heated in a 140° C. oil bath for six hours, allowed to cool to room temperature, and then is saturated with solid potassium carbonate. The mixture is extracted thrice with ethyl acetate. The combined extracts are dried over anhydrous sodium sulfate, decanted, and concentrated under reduced pressure to give N-t-butyl,N′,N′-dimethylethylenediamine as a light brown liquid (0.57 g, 56%). The crude material is carried on to the following step without further purification.
