3-氯-4-乙氧基苯胺

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

实验步骤: 1-Ethoxy-2-chloro-4-isocyanato-benzene is prepared by addition of triethylamine to a solution of 4-ethoxy-3-chlorophenylamine in EtOAc at 0-5° C. Triphosgene is added and the reaction mixture is slowly heated to reflux over 2 h. The solvent is removed in vacuo and the crude product is filtered through silica to afford the title compound. the reaction mixture is slowly heated to reflux over 2 h The solvent is removed in vacuo the crude product is filtered through silica
