実験手順

Into a magnetically stirred solution of 4-(4-chloro-1-naphthoxy)-3,5-dichloroaniline (6.00 grams, 17.72 mmol) prepared in Part B in benzene (50 milliliters) was added solid N-chlorosuccinimide (2.84 grams, 21.20 mmol). The mixture was heated to reflux for 1 hour. cooled and filtered. The solvent was evaporated under reduced pressure and the crude product when subjected to flash column chromatography (3:1 hexane:ethyl acetate) afforded pure 4-(4-chloronaphthoxy)-2.3.5-trichloroaniline (3.70 grams. 9.92 mmol, 56%). Elemental analysis of the product indicated the following:
