Into a 500 milliliter Parr bottle was charged 4-(4-chloro-1-naphthoxy)-3,5-dichloronitrobenzene (15.84 grams, 42.97 mmol) prepared in Part A and toluene (250 milliliters). The bottle was purged thoroughly with nitrogen and 5% platinum on carbon (0.50 grams) was added immediately following the purge. The reaction mixture was then hydrogenated for 1.5 hours on a rocking Parr hydrogenator at a pressure of 90-100 psi hydrogen at ambient temperature. The reaction mixture was filtered through a pad of celite and the filtrate concentrated under reduced pressure to afford pure 4-(4-chloro-1-naphthoxy)-3,5-dichloroaniline (13.99 grams, 41.31 mmol, 96%) as a white solid having a melting point of 145° C.-147° C. Elemental analysis of the white solid indicated the following:
