Procedure

100 mg (0.25 mmol) of methyl (2E)-3-{3-fluoro-2-[({[2-methoxy-5-(trifluoromethyl)phenyl]-imino}methylene)amino]phenyl}-2-propenoate (Example 18A), 45.7 mg (0.25 mmol) of 1-(3-fluorophenyl)piperazine (Example 15A) and a spatula tip of silica gel are stirred in 15 ml of dichloromethane at room temperature for 1 hour and then under reflux for 20 hours. The target compound is obtained after chromatography on silica gel (dichloromethane, dichloromethane/ethyl acetate 10:1).
