A mixture of phenyl 2-[4-(2-ethyl-4-phenyl-1H-imidazol-1-yl)phenyl]ethylcarbamate (203 mg, 0.50 mmol), 5-methylpyridine-2-sulfonamide (86 mg, 0.50 mmol) and DBU (82 μL, 0.55 mmol) in acetonitrile (5 mL) was stirred for overnight at ambient temperature. Then, the volatile components were removed by evaporation and the residue was dissolved in dichloromethane. The organic phase was washed with water, dried (MgSO4) and concentrated. The residue was purified by TLC with dichloromethane/methanol (10:1) to afford 145 mg (60%) of the title compound as white solids: MS (ESI) m/z 490 [M+H]+, 488 [M−H]−, 1H-NMR (DMSO-d6) δ 1.18 (3H, t, J=7.5 Hz), 2.37 (3H, s), 2.72-2.90 (4H, m), 3.23 (2H, q, J=6.0 Hz), 6.69 (1H, br), 7.40-7.59 (6H, m), 7.85-7.93 (4H, m), 8.24 (1H, s), 8.55 (1H, s).
