Compounds wherein W corresponds to graphic formulae L-3 and L-7 may be prepared by first selectively reacting the nitrogen of 3-amino-2-naphthol with reagents such as substituted or unsubstituted benzoyl halides, alkyl or aryl isocyanates, or active halogen bearing heterocycles, such as chloropyridine, to form 3-substituted-2-naphthols.
