実験手順
1-(5-chloro-2-fluorophenyl)ethanone (20 mg, 0.116 mmol) and 3-(morpholinosulfonyl)benzohydrazide (33.1 mg, 0.116 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 title compound (E)-N′-(1-(5-chloro-2-fluorophenyl)ethylidene)-3-(morpholinosulfonyl)benzohydrazide (10 mg, 0.022 mmol, 19.22% yield) as a solid. 1H NMR (CDCl3, 400 MHz): δ 8.26 (m, 1H), 8.09 (m, 1H), 7.80 (d, 1H, J=7.6 Hz), 7.58 (t, 1H, J=7.6 Hz), 7.37 (m, 1H), 7.21 (m, 1H), 6.95 (m, 1H), 3.61 (m, 4H), 2.90 (m, 4H), 2.29 (s, 3H). Mass [M+H]+:440.1
