1,3,5-Trichlorobenzene → HCID 13531050, compound

Participants

Reaction Steps

32.7 g (0.3 mol) of 3-aminophenol, 18.2 g (0.1 mol) of 1,3,5-trichlorobenzene, 28 g (0.2 mol) of anhydrous potassium carbonate and 150 ml of hexamethylphosphoric triamide were charged in a flask equipped with a stirrer. The mixture was maintained at 180° to 190° C. for 24 hours under stirring while passing gaseous nitrogen through it to accomplish the condensation. Then the reaction mixture was treated according to the same procedure as described in Example 1 to obtain 34.4 g of 1,3-bis(3-aminophenoxy)-5-chlorobenzene hydrochloride (yield: 85.8%).
