2,5-Dibromobenzaldehyde Use and Manufacturing

Compound WX006-1 (500.00 mg, 1.89 mmol) and potassium isopropenyl trifluoroborate (195.78 mg, 1.32 mmol) were dissolved in 1, 4-dioxane (10 mL) under nitrogen atmosphere, followed by addition of (1, 1'-bis(diphenylphosphino)ferrocene)palladium dichloride dichloromethane complex (154.34 mg, 189.00 muL), potassium carbonate (522.43 mg, 3.78 mmol) and water (4 mL). The reaction mixture was heated to 50 C and stirred for 12 hours under nitrogen atmosphere. After completion of the reaction, the mixture was cooled to room temperature, followed by addition of water (50 mL) and extraction with ethyl acetate (50 mL × 2). The organic phases were combined, washed with saturated brine (50 mL×2), dried over anhydrous sodium sulfate, filtered to remove the desiccant and concentrated under reduced pressure. The insoluble material was removed by filtration, and the obtained residue was purified by flash silica gel column chromatography (eluent: ethyl acetate/petroleum ether = 1/9) (eluent: ethyl acetate/petroleum ether = 0/9-1/9) to obtain the title compound WX006-2 (colorless liquid, 500.00 mg, yield: 77.78%). 1H NMR (400MHz, CDCl3) delta: 10.07(s, 1H), 7.96(s, 1H), 7.59-7.57(d, J = 6Hz, 1H), 7.17-7.15 (d, J = 8Hz, 1H), 5.38(s, 1H), 4.85(s, 1H), 2.11(s, 3H).
