Procedure

The procedure described above in Example 29 for Formula IIc-iii was followed, starting from 4-(4-chlorophenyl)-1H-imidazole (125 mg, 0.7 mmol) and 2-bromofuran, to prepare the desired 4-(4-chlorophenyl)-1-(furan-2-yl)-1H-imidazole (3 mg, 0.12, yield 1.7%) as a brownish solid. The HPLC purity of the final product was 95.84%. LC-MS [M+H] 245 (C13H9ClN2O+H expected 245.04). The 1H-NMR spectra was in accordance with the chemical structure.
