In reaction (1), o-aminobenzhydrazide in 70% yield is prepared by reacting the methyl ester of o-amino benzoic acid (methyl anthranilate) with 64% aqueous hydrazine. Equation (2) illustrates the preparation of 2-hydroxy-1-naphthaladehyde from beta-naphthol, paraformaldehyde, hexamethylene tetramine, acetic acid and hydrochloric acid. o-Aminobenzhydrazide and 2-hydroxy-1-naphthaldehyde are reacted, in Equation (3), to produce the preferred hydrazone, 2-hydroxy-1-naphthaldehyde-o-aminobenzoyl hydrazone in 80-90% yield.
