110-70-3, The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. N1,N2-Dimethylethane-1,2-diamine, cas is 110-70-3,the chiral-nitrogen-ligands compound. Here is a downstream synthesis route of the compound.
To a solution of N,N?-dimethylethane-1,2-diamine (40.4 g) in DCM (300 mL) was added a solution of Boc2O (10 g, 10.6 mL, 45.8 mmol) in DCM (100 mL) dropwise at 0 C over 1 hr. The reaction mixture was stirred at room temperature for 18 hrs. The organic layer was washed with saturated aqueous NaHCO3 (50 mL), brine (50 mL), dried overNa2SO4 and concentrated in vacuo. The residue was purified by column chromatography toafford tert-butyl N-methyl-N- [2-(methylamino)ethyl]carbamate (6.8 g, Compound BC-i)as a yellow oil. 1H NMR (400MHz, CDCl3) 5 ppm: 3.34 (br. s., 2H), 2.89 (s, 3H), 2.74 (t, J= 6.7 Hz, 2H), 2.46 (s, 3H), 1.47 (s, 9H).
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
