Reaction Steps

1-(2,6-Dihydroxyphenyl)ethanone (100 mg, 0.657 mmol) and benzohydrazide (89 mg, 0.657 mmol) were dissolved in methanol (4 mL) in the presence of acetic acid as a catalyst and then the reaction mixture was heated via microwave irradiation to 120° C. for 30 min. Following cooling, the solvent was removed by vacuum, and the resulting crude material was purified by flash column chromatography (2% CH3OH/CH2Cl2) affording the title compound (100 mg) as a solid. 1H NMR (400 MHz, CD3OD): δ 7.59 (m, 2H), 7.49 (m, 1H), 7.39 (m, 2H), 7.11 (t, 1H, J=8.0 Hz), 6.45 (m, 2H), 2.35 (s, 3H). ESI-MS: 271.1 [M+H]+.
