実験手順
In a manner similar to the method described in example 1a, 6-chlorooxindole (2 g, 11.4 mmol) was reacted with 4-chloro-benzaldehyde (1.91 g, 13.6 mmol) (1.53 g, 13.6 mmol) (Aldrich) and piperidine (1.34 mL, 13.6 mmol) in methanol to give a mixture of E- and Z-6-chloro-3-(4-chloro-benzylidene)-1,3-dihydro-indol-2-one as a yellow solid (Yield: 3.3 g, 100%).
