Procedure

5-Bromo-2-(2,2,2-trifluoro-ethoxy)-benzaldehyde prepared in Example 232a (11 g, 39 mmol) and 6-chlorooxindole (5.4 g, 32 mmol) were mixed in anhydrous methanol (50 mL) at room temperature. Then pyrrolidine (2.7 g, 39 mmol) was added dropwise. The mixture was then heated at 70° C. for 3 h. After cooled to 4° C., the mixture was filtered and resulting precipitate was collected, dried to give E/Z-3-[5-Bromo-2-(2,2,2-trifluoro-ethoxy)-benzylidene]-6-chloro-1,3-dihydro-indol-2-one as yellow solid (9.6 g).
