N1,N2-Dimethylethane-1,2-diamine, cas is 110-70-3, it is a common heterocyclic compound, the chiral-nitrogen-ligands compound, its synthesis route is as follows.
To a stirred solution of Lambda/,Lambda/’-dimethylethylene diamine (3.66 mL, 34 mmol) in dichloromethane (40 mL) at 0C was added dropwise a solution of di-tert-butyl dicarbonate (2.4 g, 11 mmol) in dichloromethane (20 mL) and allowed to warm to room temperature overnight, concentrated under reduced pressure, diluted with EtOAc (100 mL), washed with water (2 * 100 mL), brine (100 mL), dried and concentrated under reduced pressure to give the title product 91 as a colourless oil (1.54 g, 74% yield). 1H NMR (400 MHz, CDCI3) delta 3.26 (t, J = 6.15 Hz, 2H), 2.81 (s, 3H), 2.66 (t, J = 6.57 Hz, 2H), 2.38 (s, 3H), 9.28 (s, 9H) ppm.
With the rapid development of chemical substances, we look forward to future research findings about 110-70-3
