Developments in anticonvulsants

1-{(E)-[3-(1H-Imidazol-1-yl)-1-(4-meth-oxy-phen-yl)propyl-idene]amino}-3-(2-methyl-phen-yl)urea

In the title compound, C(21)H(23)N(5)O(2), the conformation about the imine bond [1.287 (3) Å] is E. Overall, the mol-ecule has a disk shape, the dihedral angles between the imidazole ring and the meth-oxy-phenyl and methyl-phenyl rings being 49.42 (13) and 42.62 (13)°, respectively; the dihedral angle between the benzene rings is 20.11 (11)°. In the urea moiety, the N-H atoms are anti to each other and one of these forms an intra-molecular N-H⋯N hydrogen bond. In the crystal, centrosymmetric dimers are formed via N-H⋯N(imidazole) hydrogen bonds, which are connected into a three-dimensional architecture by C-H⋯O(carbon-yl) and (methyl-ene)C-H⋯π inter-actions. The crystal studied was a non-merohedral twin with a minor component of 48.3 (1)%.
