{4-[4,5-Bis-(4-chloro-phenyl)-1-isobutyryl-4,5-dihydro-1H-imidazol-2-yl]-phenoxy}-acetic acid ethyl ester. HR-MS (ES, m/z) calculated for C29H29N2O4Cl2[(M+H)+]539.1499, observed 539.1506. The starting ethyl (4-cyano-phenoxy)-acetate was prepared from 4-hydroxy-benzonitrile and ethyl bromoacetate as described in Kirkiacharian, S.; Goma, J. R. et al. Ann. Pharm. Fr. 1989, 47, 16-23.
