Furan-3-boronic acid (1.0 g, 8.93 mmol), bromo benzene (1.26 g, 8.04 mmol) and sodium carbonate (1.89 g, 17.86 mmol) were dissolved in a mixture of toluene (15 mL) and methanol (5 mL) and purged with argon for 15 min. Tetrakis palladium (0) (20 mg) was added and the mixture again degassed for 15 min. The reaction was heated at 80° C. for 4 h and the resultant solids which formed were filtered and the filtrate was concentrated in vacuo to give a crude residue. Purification by flash chromatography over silica gel (100-200 mesh) using 2% ethyl acetate/petroleum ether as eluent afforded 3-phenylfuran (0.9 g, 70%).
