Tert-Butylamine → 1,2-Ethanediamine,N2-(1,1-dimethylethyl)-N1,N1-dimethyl-

Into a 50 mL-volume flask equipped with a stirrer, a thermometer and a dropping funnel were placed 16 g (0.22 mol) of t-butylamine, 5.0 g (35 mmol) of 2-(dimethylamino)ethyl chloride hydrochloride and 1 ml of water. And then, the mixture was reacted at 70° C. for 10 hours. After the completion of the reaction, the reaction solution was subjected to extraction with 25 ml of hexane twice, and the hexane layer was concentrated under reduced pressure. The resultant concentrate was distilled under reduced pressure (60° C., 2.4 kPa), to provide 3.0 g of 1-(t-butylamino)-2-dimethylaminoethane. (Isolation yield: 60%)
