As a common heterocyclic compound, it belongs to chiral-nitrogen-ligands compound, name is N1,N2-Dimethylethane-1,2-diamine, and cas is 110-70-3, its synthesis route is as follows.
Example 71Synthesis of tert-butyl methyl [2-(methylamino)ethyl]carbamate (VI-I) A solution of di-tert-butyl dicarbonate (2.18 g, 0.01 mol) in CH2Cl2 (120 mL) was added dropwise to a solution of N,N’-Dimethyl-ethane-1,2-diamine (1.76 g, 0.02 mol) in CH2Cl2 (40 mL) over 6 h with vigorous stirring. The reaction mixture was continued to stir for a further 18 h at room temperature. Then the solvent was concentrated in vacuo to give an oily residue, which was dissolved in 60 mL of 2M Na2CO3 aqueous solution, and extracted with CH2Cl2 (30 mL x 2). The combined organic layers were washed with 2M Na2CO3 (30 mL x 2), and dried over anhydrous MgSO4. The solvent was evaporated in vacuo to yield the product, which was purified by column chromatography (silica gel, CH2Cl2 : MeOH, 9: 1) to afford colorless oil (VI-I, 1.15 g, 61%)
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of N1,N2-Dimethylethane-1,2-diamine, 110-70-3
