N-(4-(2-(4-Aminophenyl)ethyl)-1,3-thiazol-2-yl)acetamide (100 mg) prepared in a similar manner according to Step 6 of Production Example 1, methyl ethanimidothioate hydriodide (166 mg) and methanol (3 ml) were combined, and refluxed for 1.5 hours. After cooled to room temperature, the mixture was concentrated in vacuo. The residue was purified by flash column chromatography over NH silica gel with chloroform/methanol (20:1→10:1) as an eluent to give N-(4-{2-[4-(ethanimidoylamino)phenyl]ethyl}-1,3-thiazol-2-yl)acetamide (165 mg) as a pale yellow amorphous substance.
