Reaction Steps
Add benzophenone imine (3.56 g, 2 mmol), (±)-2,2′-bis(diphenylphosphino)-1,1′-binaphthalene (BINAP, 43 mg, 0.069 mmol), tris(dibenzylideneacetone)dipalladium [Pd2(dba)3, 90 mg, 0.098 mmol] and cesium carbonate (858 mg, 2.63 mmol) to the solution of 3-(3-bromo-5-(trifluoromethyl)phenyl)-5-methyloxazolidin-2-one (430 mg, 1.32 mmol) in dioxane (5 mL). Stir the mixture under nitrogen atmosphere at 100° C. overnight. TLC (PE:EtOAc=1:1) shows the reaction is complete. Filter the mixture and concentrate the filtrate to yield the crude product. Purify by flash chromatography (silica gel, PE:EtOAc=1:1) to afford the product (500 mg, 89%).
