110-70-3, N1,N2-Dimethylethane-1,2-diamine is a chiral-nitrogen-ligands compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
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.
As the paragraph descriping shows that 110-70-3 is playing an increasingly important role.
