Name is N1,N2-Dimethylethane-1,2-diamine, as a common heterocyclic compound, it belongs to chiral-nitrogen-ligands compound, and cas is 110-70-3, its synthesis route is as follows.,110-70-3
Preparation of Methyl-(2-methylamino-ethyl)-carbamic acid tert-butyl esterTo an ice-cooled solution of N,N’-dimethyethylenediamine (10 ml_, 91.0 mmol) in dry THF (150 ml.) was added a solution of BoC2O (4.97 g, 22.8 mmol) in dry THF (50 ml.) over 30 minutes. The reaction mixture was stirred for 1 h at 00C then at rt overnight, and concentrated in vacuo. The resulting residue was taken up in a mixture of EA and a sat.NH4CI solution. The organic layer was separated, washed with brine, dried (MgSO4), filtered and concentrated under reduced pressure. FC (10 % MeOH in DCM) afforded the title compound as a yellow oil (2.90 g, 17%). LC-MS (analytic A, Zorbax SB-AQ column, acidic conditions): tR = 0.50 min; [M+H]+ 189.40.
With the complex challenges of chemical substances, we look forward to future research findings about N1,N2-Dimethylethane-1,2-diamine
