Introduction of a new synthetic route about 110-70-3

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

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., 110-70-3

To a solution of compound 9-3 (10 g, 36.5 mmol) in EtOH was added dropwise compound 9-3-1 (39 mL, 365 mmol) under nitrogen atmosphere at 0 C., and then the reaction solution was stirred at 20 C. for 2 h, followed by concentration. The residue was purified by column chromatography to give the title compound 9-4 (yellow solid, 5.5 g, Yield 56%). 1H NMR (400 MHz, CDCl3): delta ppm 8.16 (d, J=8.8 Hz, 2H), 7.59 (d, J=8.8 Hz, 2H), 3.80 (s, 1H), 3.60-3.80 (m, 1H), 3.15-3.30 (m, 1H), 3.00-3.10 (m, 1H), 2.93 (s, 3H), 2.60-2.75 (m, 1H), 2.15 (s, 3H).

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
