2-(4-氯-2-甲酰基苯氧基)乙腈

反应条件: temp:70.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: To the mixture of 6-chlorooxindole (18.4 g, 0.110 mol) and (4-chloro-2-formyl-phenoxy)-acetonitrile (21.5 g, 0.110 mol) in methanol (200 mL) was added pyrrolidine (8.60 g, 0.121 mol) dropwise. Then the mixture was heated at 70° C. for 2 h. After cooled to room temperature, the mixture was filtered. The precipitate was collected and dried to give the title compound as a yellow solid (8.5 g). After cooled to room temperature the mixture was filtered The precipitate was collected dried

实验步骤: At room temperature, a mixture of (4-chloro-2-[1,3]dioxolan-2-yl-phenoxy)-acetonitrile (28.68 g, 0.12 mol) and trifluoroacetic acid (41.04 g, 0.36 mol) in EtOAc (500 mL) was stirred overnight. Then the solution was washed with water, saturated NaHCO3 solution twice, dried over anhydrous Na2SO4, and concentrated to give crude product (22 g). The crude product was directly used for next step without further purification. Then the solution was washed with water, saturated NaHCO3 solution twice dried over anhydrous Na2SO4 concentrated
