Procedure
The coupling component used in this Example was obtained by reacting methyl 2-hydroxy-3-naphthoate with dimethylamino propylamine in toluene to obtain N,N-dimethyl-N-3-(3-hydroxy-2-naphthamido)propylamine, and converting the amide compound isolated by filtration, with dimethylsufuric acid in methanol, to a quaternary ammonium form. Further, the amide compound may also be readily prepared via 2-hydroxy-3-napthoic acid chloride.
