Reaction Steps

4-Bromo-1-phenyl-1H-imidazole (200 mg, 0.9 mmol), furan-2-ylboronic acid (342 mg, 3 mmol), PEPPSI-iPr (18 mg, 0.026 mmol), and K2CO3 (640 mg, 4.64 mmol) were then combined in toluene-methanol (1:1) (4 ml). The reaction mixture was heated under microwave at 80° C. for 20 minutes. It was then filtered and washed with toluene-MeOH (5 ml), and the filtrate was concentrated to yield a crude mixture. The crude mixture was then column purified using 15-20% ethyl acetate/hexanes to afford the desired 4-(furan-2-yl)-1-phenyl-1H-imidazole (50 mg, 0.19 mmol, yield 21.4%) as a brown sticky liquid with an HPLC purity of 95.5%. LC-MS [M+H] 211 (C13H10N2O+H expected 211.08). The 1H-NMR spectra was in accordance with the chemical structure.
