Procedure

To a mixture of 6-chlorooxindole (0.84 g, 5 mmol) and 4-(4-chloro-2-formyl-phenoxy)-piperidine-1-carboxylic acid tert-butyl ester (1.7 g, 5 mmol) in methanol (10 mL) was added pyrrolidine (0.4 mL, 5 mmol) dropwise. The mixture was then heated at 70° C. for 3 h. After cooled to 4° C., the mixture was filtered and the precipitate was collected, dried to give the title compound as a bright yellow solid (1 g).
