3-Chloro-propanoic acid (4.34 g, 0.04 mol) was dissolved in 5.0 mL of water on ice bath and carefully neutralized with cold water solution of 5.0 mL NaOH (1.60 g, 0.04 mol). Meso-1,2-diphenyl-ethylenediamine (4.24 g, 0.02 mol) was added to this solution. The mixture was being stirred for 4 h at 90 C, and during this period 5.0 mL NaOH water soltion (1.60 g, 0.04 mol) was introduced. After that, 5.6 mL 6 mol/L HCl was added and resulting solution was evaporated to the volume of 7.0 mL; 6.0 mL conc. HCl, 6.0 mL of ethanol and 6.0 mL of ether were added to the mixture. The white precipitate of meso-1,2-diphenyl-ethylenediamine-N,N’-di-3-propanoic acid dihydrochloride monohydrate, H2-1,2-dpheddp 2HCl H2O was separated by filtration and refined with solution water: ethanol = 1: 2. Yield: 4.00 g (44.69%). Anal. Calcd. for H2-1,2-dpheddp*2HCl*H2O = C20H28Cl2N2O5 (Mr = 447.344): C, 53.69; H, 6.31; N, 6.26. Found: C, 53.88; H, 6.70; N, 6.08.
29841-69-8, 29841-69-8 (1S,2S)-(-)-1,2-Diphenylethylenediamine 6931238, acatalyst-ligand compound, is more and more widely used in various fields.
