2050-25-1 , The common heterocyclic compound, 2050-25-1, name is 2-(2-(Benzyloxy)ethoxy)ethanol, molecular formula is C11H16O3, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.

Under a nitrogen atmosphere, silver trifluoromethane sulfonate (19.64 g, 76.44 mmol), lithium trifluoromethane sulfonate (3.97 g, 25.48 mmol), 1-(chloromethyl)-4-fluoro- 1,4-diazoniabicyclo[2.2.2]octane bis(tetrafluoroborate) (18.05 g, 50.96 mmol) and potassium fluoride (5.92 g, 101.92 mmol) were mixed.2-(2-benzyloxyethoxy)ethanol (5 g, 25.48 mmol), trimethyl(1,1,2,2,2-pentafluoroethyl)silane (14.69 g, 76.44 mmol), EtOAc (20 mL), trifluoromethylbenzene (20 mL), and 2-fluoropyridine (7.42 g, 76.44 mmol) were then added under N2 atmosphere in this order. The reaction mixture was stirred under N2 atmosphere for 60 h at 30 C then filtered through a plug of silica (eluting with EtOAc). The filtrate was collected and concentrated. The residue was purified via silica gel chromatography (PE:EtOAc = 25:1) to obtain 2-[2-(1,1,2,2,2-pentafluoroethoxy)ethoxy]ethoxymethylbenzene (2.5 g, 31% yield) as a light yellow liquid. 1H NMR (400 MHz, CDCl3) d 7.36- 7.24 (m, 5H), 4.56 (s, 2H), 4.17- 4.11 (m, 2H), 3.76- 3.72 (m, 2H), 3.71- 3.65 (m, 2H), 3.65- 3.60 (m, 2H). 19F NMR (376 MHz, CDCl3) d -90.77 (s), -86.02 (s).

According to the analysis of related databases, 2050-25-1, the application of this compound in the production field has become more and more popular.
