Reaktionsschritte
2-(3,4-Dichlorophenyl)-4-(1-hydrazonoethyl)-thiophen-3-ol (25 mg, 0.08 mmol) prepared in Reference Synthetic Example 13 in dimethylformamide (0.25 mL) was stirred with 6-isothiocyanato-2,3-dihydrobenzo[1,4]dioxine (24 mg, 0.13 mmol, at 30° C. for 4 hours. Methanol and water were added to the reaction solution, and the resulting crystals were collected by filtration, washed and dried to give 28 mg of the desired product (yield 65%).
