実験手順

1-(5-chloro-2-nitrophenyl)ethanone (30 mg, 0.150 mmol) and 3-(morpholinosulfonyl)benzohydrazide (42.9 mg, 0.150 mmol) was dissolved in Methanol (Volume: 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. Reaction was monitored by TLC. After completion of the reaction, following cooling, the solvent was removed by vacuum and the resulting crude material was purified by flash column chromatography (2% CH3OH/CH2Cl2), afforded the product (E)-N′-(1-(5-chloro-2-nitrophenyl)ethylidene)-3-(morpholinosulfonyl)benzohydrazide (15 mg, 0.030 mmol, 20.09% yield) as a solid. 1H NMR (CDCl3, 400 MHz): δ 8.20 (m, 1H), 8.07 (m, 1H), 7.88 (m, 1H), 7.66 (m, 1H), 7.51 (m, 2H), 7.39 (m, 1H), 3.69 (m, 4H), 2.99 (m, 4H), 2.29 (s, 3H). Mass [M+H]+:468.0
