実験手順

A solution of 2-(3,4-dichlorophenyl)-4-(1-hydrazonoethyl)thiophen-3-ol (30 mg, 0.10 mmol) prepared in Reference Synthetic Example 1 and methyl 2-isothiocyanatoacetate (20 mg, 0.15 mmol) in dimethyl formamide (300 μL) was stirred at room temperature, 40° C. and 50° C. for 2 hours, respectively. After addition of methanol-water, the solution was stirred at room temperature for 0.5 hour, and the resulting crystals were collected by filtration as the desired product (yield 0.72%).
