Procedure
Starting with 3-(4'-bromomethyl phenyl)-2-bromobenzofuran, nitration with dinitrogen tetraoxide in acetic acid in the presence of cyclohexene-4-carboxylic acid provides 3-(4'bromomethyl phenyl)-2-nitrobenzofuran which is reacted according to the method of Example 1 with N,N'-dimethylaminoethylamine. The product obtained is 3-[4'-(N,N'-dimethylaminoethylaminomethyl)phenyl]-2-nitrobenzofuran having the structure ##STR35##
