Procedure
A suspension of ethyl 4-(4-methoxyphenyl)-2-phenyl-1H-imidazole-5-carboxylate (0.078 g, 0.23 mmol) in aqueous (28%) ammonia (4.5 ml) was heated in the microwave for 35 minutes at 150° C. The solvent was then removed in vacuo and the residue was purified by preparative HPLC to afford 4-(4-methoxyphenyl)-2-phenyl-1H-imidazole-5-carboxamide (0.0109 g, 0.04 mmol, 16%) as a white solid. 1H NMR (DMSO) δ 3.82 (3H, s), 7.01 (2H, d), 7.10 (1H, br. s), 7.39-7.43 (2H, m), 7.49 (2H, dd), 7.85 (2H, d), 8.10 (2H, m). LCMS (2) Rt: 2.46 min; m/z (ES+) 294.
