Reaction Conditions:
with potassium acetate;palladium diacetate at 80; under 760.051 Torr; for 24 h;
Steps:
13 Preparation of 4-bromo-2,5-dimethylbenzoic acid
0.6 mmol of potassium acetate, 0.3 mmol of 4-bromo-3-methylbenzoic acid,Palladium acetate 0.03 mmol, peroxydi-tert-butyl ether 0.6 mmol,0.8 mL of hexafluoroisopropanol was added to a 15 mL reaction tube and placed in an oil bath at 80 ° C.Reacting in an air atmosphere at a pressure of 1 atmosphere for 24 hours;After cooling to room temperature, the reaction solution was diluted with ethyl acetate and washed with water.The organic phase is dried over anhydrous Na2SO4.Filtered, concentrated,Purification by thin layer chromatography gave 41 mg of the desired product.White solid in 60% yield.
