Procedure

In a manner similar to the method described in example 1a, 6-chlorooxindole (1.2 g, 7.2 mmol) was reacted with 4-chloro-thiophene-2-carbaldehyde (1.05 g, 7.2 mmol) and pyrrolidine (0.7 g, 9.9 mmol) to give E/Z-6-chloro-3-(4-chloro-thiophen-2-ylmethylene)-1,3-dihydro-indol-2-one as a yellow solid (Yield 1.3 g, 62%)
