実験手順

550 mg (1.39 mmol) of methyl (2E)-3-{3-fluoro-2-[({[2-methoxy-5-(trifluoromethyl)phenyl]-imino}methylene)amino]phenyl}-2-propenoate (Example 18A) and 251 mg (1.39 mmol) of 1-(4-fluorophenyl)piperazine are stirred in the presence of a spatula tip of silica gel in 15 ml of dichloromethane for 1 hour. After 90 hours of stirring under reflux, the product is purified by chromatography on silica gel (dichloromethane, dichloromethane/ethyl acetate 10:1).
