실험 절차

To a stirred solution of methyl (2Z,4E)-5-(benzothiophen-2-yl)-2-methoxy-2,4-pentadienoate (107 mg, 0.39 mmol) in EtOH/water 1/1 (10 ml) potassium hydroxide (47 mg, 0.78 mmol) was added. The solution was refluxed for 1 hour, then it was treated as seen in example 2. Pure title compound (54 mg, 0.207 mmol, yield 53.2%) was obtained as yellow crystals.
