Ethyl-Lophine, 1-ethyl-2,4,5-triphenyl-1H-imidazole, C23H20N2, was synthesized as a precursor for large organic cations in ionic liquids using an improved microwave-assisted method. The title compound and a precursor compound were characterized by NMR, IR, and DSC thermal measurements, as well as elemental analyses. The crystal structure of ethyl-lophine was determined by single-crystal X-ray structure analysis (triclinic, P1̅, a = 10.1137(3), b = 12.4935(4), c = 14.6351(4) Å, α =98.182(2)°, β =90.694(2)°, γ =102.666(2)°, Z = 4, wR2 = 0.1030 for 611 refined parameters).
