To a stirred solution of 3-[(2-naphthyl)methoxy]-5-nitrobenzhydrazide (0.30 g, 0.89 mmol) and triethylamine (0.14 mL, 0.98 mmol) in DMA (25 mL) at room temperature was added benzoyl bromide (0.11 mL, 0.89 mmol), and stirring was continued overnight. Yellowish solution was poured onto ice-water (50 g) and set aside for 24 h. Precipitate formed was filtered, washed with water, and air-dried. Off-white solid, yield 0.34 g (87%). 1H NMR (DMSO-d6, 400 MHz), δ: 10.92 (s, 1H); 10.66 (s, 1H); 8.12-7.89 (m, 8H); 7.67-7.50 (m, 6H); 5.53 (s, 2H).
