Reaktionsschritte
The particularly preferred substituted aromatic hydrazone 2-hydroxy-1-naphthaldehyde-p-(t-butyl)-benzoyl hydrazone is prepared in a manner similar to the preparation of 2-hydroxy-1-naphthaldehyde-o-aminobenzoyl hydrazone, Equations (1) through (3) above. Since the ester of p-(t-butyl)-benzoic acid is not available the preparation of this hydrazone requires the additional step of esterification of the benzoic acid. The ester of p-(t-butyl)-benzoic acid is reacted with hydrazine to produce p-(t-butyl)-benzhydrazide. This hydrazide is then reacted with 2-hydroxy-1-naphthaldehyde to yield 2-hydroxy-1-naphthaldehyde-p-(t-butyl)-benzoyl hydrazone.
