Sodium Carbonate → HCID 86639498, compound

Participants

Reaction Steps

To a suspension of 2-bromo-5-hydroxybenzaldehyde (300 mg, 1.49 mmol), sodium carbonate (190 mg, 1.79 mmol), and 1-naphthaleneboronic acid (384 mg, 2.23 mmol) in 3.0 mL of N,N-dimethylformamide/water (2:1) was added palladium acetate (18 mg, 80 μmol) under nitrogen. After being stirred at room temperature overnight, the reaction mixture was filtered. The filtrate was diluted with ethyl acetate, and the solution was washed with saturated NaHCO3 aqueous solution, brine, and dried over MgSO4. After filtration, the filtrate was concentrated in vacuo, and the residue was purified by silica gel column chromatography (hexane/ethyl acetate=85/15 to 75/25) to obtain the title compound as a white solid (274 mg, 74%).
