実験手順

To the mixture of 6-chlorooxindole (9.3 g, 55.7 mmol) and 2-(4-chloro-2-formyl-phenoxy)-2-propyl-pentanoic acid ethyl ester (14 g, 42.9 mmol) in methanol (100 mL) was added pyrrolidine (3.3 g, 47.2 mmol) dropwise. The mixture was then heated at 80° C. for 2 h. After cooled to room temperature, the mixture was concentrated. The residue was purified by flash column to give the title compound (4.2 g).
