Versuchsvorschrift

700 mg (1.78 mmol) of methyl (2E)-3-{3-fluoro-2-[({[2-methoxy-5-(trifluoromethyl)phenyl]-imino}methylene)amino]phenyl}-2-propenoate (Example 18A), 341 mg (1.78 mmol) of 1-(3-methoxyphenyl)piperazine and a spatula tip of silica gel are stirred in 20 ml of dichloromethane at room temperature for one hour and then under reflux for 35 hours. The target compound is obtained after purification on silica gel (dichloromethane, dichloromethane/ethyl acetate 10:1).
