Analogously to Example 1a) 5-bromo-pyridine-2-carbonitrile was reacted with 2-trifluoromethyl-4-methoxy-aniline. After chromatographic purification through silica gel (petroleum ether with 10 to 30% ethyl acetate) the 4-(4-methoxy-2-trifluoromethyl-phenyl-amino)-benzonitrile was obtained in a yield of 97.4% of theory.
