実験手順

To 10.5 g of N,N′-dimethylethylenediamine in 250 ml of THF was added 26 g of tosylchloride (TsCl) in small portions at room temperature. After 16 hours, solvents were evaporated and the residue was apportioned between H2O and CH2Cl2. A CH2C2 layer was separated and washed with brine, dried (MgSO4), filtered, and concentrated under reduced pressure. About 26.5 g of N,N-dimethyl-N′-tosylethylenediamine (93%) was produced. The reaction steps are shown below:
