Procedure

To a stirred and cooled (0° C.) mixture of 14.6 parts of 4-[(4-chlorophenyl)(1H-imidazol-1-yl)methyl]benzenamine, 60.9 parts of benzene and 6.86 parts of pyridine was added a solution of 10.6 parts of 3-phenyl-2-propenoyl chloride in 17.4 parts of benzene under a nitrogen atmosphere. After stirring overnight at room temperature, the reaction mixture was basified and extracted with ethyl acetate. The extract was washed with water, dried, filtered and evaporated. The residue was crystallized from dichloromethane. The product was filtered off and dried, yielding 17.7 parts (83.8%) of N-[4-[(4-chlorophenyl) (1H-imidazol-1-yl)methyl]phenyl]-3-phenyl-2-propenamide; top. 244° C.(interm. 50).
