Pyrrolidine → HCID 86760820、化合物

Acetic acid 2-(4-chloro-2-formyl-phenoxy)-ethyl ester (1.5 g, 9.3 mmol) and 6-chlorooxindole (2.7 g, 11.2 mmol) were mixed in anhydrous methanol (20 mL) at room temperature. Then Pyrrolidine (0.8 g, 11.2 mmol) was added slowly. The reaction mixture was heated at 70° C. for 3 h, then cooled to r.t and the precipitation was collected by filtration to obtain title compound as a yellow solid (1.4 g).
