Related Products of 169247-46-5,Some common heterocyclic compound, 169247-46-5, name is 1-(Benzyloxy)-4-bromo-2-(trifluoromethyl)benzene, molecular formula is C14H10BrF3O, 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.

Then, 5.10 g of 4-bromo-2-trifluoromethyl-1-benzyloxybenzene, 2.34 g of p-ethoxyphenol, 2.13 g of potassium carbonate, 100 mg of copper and 200 mg of cuprous chloride were charged into a reaction vessel, and stirred at 130° C. to 140° C. for 5 hours. The reaction solution was cooled to room temperature, poured into ice-water and then acidified by adding 10percent hydrochloric acid. The solution was extracted twice with 100 ml of diethyl ether. Then, the ether layers were combined, washed with water, dried over anhydrous magnesium sulfate and concentrated to give a crude product. This crude product was subjected to silica gel chromatography to give 2.50 g of 2-trifluoromethyl-4-(4-ethoxyphenoxy)-1-benzyloxybenzene (yield, 41percent).

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 1-(Benzyloxy)-4-bromo-2-(trifluoromethyl)benzene, its application will become more common.

Reference of 169247-46-5, These common heterocyclic compound, 169247-46-5, name is 1-(Benzyloxy)-4-bromo-2-(trifluoromethyl)benzene, 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.

A 100 mL round bottom flask was charged with EXAMPLE 49B (1.9Og, 5.74 mmol), 4,4,4′,4′,5,5,5′,5′-octamethyl-2,2′-bi(l,3,2-dioxaborolane) (1.75g, 6.89 mmol), [l,r-bis(diphenylphosphino)ferrocene]dichloropalladium(II) dichloromethane (0.234 g, 0.287 mmol), diphenylphosphinoferrocine (0.159g, 0.287 mmol) and potassium acetate (1.689g, 17.21 mmol) in 50 mL dioxane. The mixture was degassed with N2 and heated at 800C overnight, diluted with water, and extracted into ethyl acetate. The organics were washed with brine and dried (MgSO4), filtered, and concentrated. The crude product was purified on silica gel eluting with 0-10percent ethyl acetate/hexane to provide the title compound. MS (DCI(+)) m/e 396 (M+NH4)+; 1H NMR (300 MHz, dimethylsulfoxide- d6) delta ppm 7.64 (dd, 1 H), 7.56-7.16 (m, 7 H), 5.26 (s, 2 H), 1.29 (s, 12 H).

The synthetic route of 169247-46-5 has been constantly updated, and we look forward to future research findings.
