Reaction Steps

A mixture of 0,277 mol of 1,4-benzenediamine, 0,017 mol of methyl 2-hydroxy benzoate and 10 grams of potassium carbonate is stirred for 1 hour at 190° C. Then there are added 0,049 mol of 1-chloro-4-(trifluoromethylsulfonyl)benzene and stirring at 190° C. is continued for 3 hours. The reaction mixture is cooled and stirred in 2000 ml of water. The precipitated product is filtered off, washed with water, dried and crystallized from a mixture of ethanol and water, yielding 2.3 grams of N-[4-(trifluoromethylsulfonyl)phenyl]-1,4-benzenediamine.
