Ethylcarbazate (0.49 g, 4.7 mmol) was added to a solution of 2,2´-dihydroxybenzophenone (1 g, 4.67 mmol) in propanol-1 (10 mL). The reaction mixture was refluxed for 24 hours. It was then allowed to cool at room temperature. Subsequently, it was stored in the refrigerator overnight. The precipitation which was formed was then filtered to give the desired hydrazone (1.26 g, 90 %). The product was identified by 1H NMR, 13C NMR and MS and it was subjected to elemental analysis without further purification.M.p. 177-179 °C.1H NMR (300 MHz, DMSO-d6): 1.28 (t, 3H), 4.20 (q, 2H), 6.73-6.81 (m, 2H), 6.99-7.13 (m, 4H), 7.31-7.45 (m, 2H), 9.96 (s, 2H), 12.72 (s, 1H).13C NMR (75 MHz, DMSO-d6): 14.4, 61.3, 116.4, 116.9, 117.2, 118.4, 119.5 (2 carbons), 129.5 (2 carbons), 130.5, 131.2, 152.6, 153.5, 154.7, 158.2.MS m/z (AP+): 301 [M+1]+, 273, 255, 212.Anal.
