To the mixture of 6-chloro-1,3-dihydro-indol-2-one (0.73 g, 4.4 mmol) and 2-(4-Chloro-5-fluoro-2-formyl-phenoxy)-2-methyl-propionic acid methyl ester (1 g, 3.65 mmol) in methanol (15 mL) was added pyrrolidine (0.26 g, 4.4 mmol) dropwise. Then the mixture was heated at 70° C. for 1 h. After cooled to room temperature, the mixture was concentrated to give the crude product which was used for the next step reaction without further purification.
