Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 6338-55-2, name is 2-(2-(2-Aminoethoxy)ethoxy)ethanol. This compound has unique chemical properties. The synthetic route is as follows. 6338-55-2
A solution of the amino alcohol (620) (313.6 g, 2.1mol) in THF (3.5 L) was treated, portion- wise, with N-(Benzyloxycarbonyloxy)succinimide (621) (550 g, 2.21mol). Once the reaction was complete (18 h) the THF was removed under reduced pressure and the residue dissolved in CH2Cl2 (2.5 L), then washed with an equal volume of HCl (1 M), NaHCO3 (Sat. Aq.), H2O and brine. The organic extract was dried (MgSO4), filtered and concentrated. The crude material (600g) was subjected to chromatography (4kg silica; 1-12% CH3OH-CH2Cl2) to yield HO- Trig-NHZ (622) (468g, 78%) as a clear-yellow viscous oil.
At the same time, in my other blogs, there are other synthetic methods of this type of compound,6338-55-2, 2-(2-(2-Aminoethoxy)ethoxy)ethanol, and friends who are interested can also refer to it.
