A mixture of 1-{3-[(2-naphthyl)methoxy]-5-nitrobenzoyl}-2-benzoylhydrazine (0.34 g, 0.77 mmol), Pd/C (10%, 0.35 g), EtOH (10 mL), and DMF (10 mL) was hydrogenated in Parr apparatus (H2 pressure—30 psi) at room temperature for 1.5 h. Catalyst was filtered off, and filtrate concentrated in vacuo to give a slurry of white needles, which were filtered and washed with EtOH (3×25 mL). Yield 0.20 g (96%). 1H NMR (DMSO-d6, 400 MHz), δ: 10.37 (s, 1H); 10.12 (s, 1H); 9.20 (s, 1H); 7.91 (d, J=7.0 Hz, 2H); 7.62-7.48 (m, 3H); 6.54 (s, 1H); 5.46 (s, 1H); 6.19 (s, 1H); 5.18 (br.s, 2H).
