| Product | 2-Hydroxy-1-naphthaldehyde-o-aminobenzoyl hydrazone | HCID 3084951 | — |
Reaction Steps
The hydrazone is prepared by refluxing 30.2 g (0.20 mol) o-aminobenzhydrazide, 34.4 g (0.20 mol) 2-hydroxy-1-naphthaldehyde and 250 ml toluene in a 500 ml flask for 1 hour. The solid formed is collected on a filter and washed with hot ethanol yielding 40 g of yellow 2-hydroxy-1-naphthaldehyde-o-aminobenzoyl hydrazone, melting at 188°-191° C.
