実験手順

3-(4-Chloro-2-formyl-phenoxy)-2,2-dimethyl-propionic acid methyl ester (6.7 g, 25 mmol) and 6-Chlorooxindole (4.35 g, 25 mmol) were mixed in anhydrous methanol (20 mL). Then pyrrolidine (2 mL, 25 mmol) was added slowly at r.t. The mixture was heated at 70° C. for 3 h and cooled to room temperature. The precipitate was collected by filtration to give title compound as a yellow solid (Yield: 7 g, 67%).
