110-70-3, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. N1,N2-Dimethylethane-1,2-diamine, cas is 110-70-3,the chiral-nitrogen-ligands compound, it is a common compound, a new synthetic route is introduced below.
Add in a 100mL single-mouth bottleN1,N2-dimethylethyl-1,2-diamine (4g, 45mmol), cooled to about 0 C in an ice bath,Then (Boc) 2O (5 g, 23 mmol) in DCM (20 mL)The temperature was raised to 25 C and the reaction was stirred for 4 h.Concentrated under reduced pressure, a saturated sodium carbonate solution was added to the residue, and extracted three times with ethyl acetate (30 mL¡Á3).The organic phase was combined, washed three times with saturated brine (20 mL¡Á3) and dried over anhydrous sodiumThe mixture was suction filtered under reduced pressure, and the filtrate was evaporated.The crude product was purified by column chromatography eluting with EtOAc EtOAcConcentration under reduced pressure gave 2.1 g of a yellow oil.
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
