Procedure

3-[5-(4-Amidino-2-fluorophenoxycarbonyl)thiophen-2-yl]propanoic acid trifluoroacetic acid salt (38 mg, 0.084 mmol) was dissolved in thionyl chloride (500 μL), and the mixture was stirred at room temperature for 20 minutes. The reaction mixture was concentrated under reduced pressure, M-21 (18.8 mg, 0.11 mmol), dichloromethane (200 μL) and pyridine (300 μL) were added to the obtained residue, and the mixture was stirred for 90 minutes. The reaction mixture was concentrated under reduced pressure, trifluoroacetic acid (500 μL) was added to the obtained residue, and the mixture was stirred at room temperature for 30 minutes. The reaction mixture was concentrated under reduced pressure, and the obtained residue was purified by high performance liquid chromatography (acetonitrile-water, each containing 0.1% trifluoroacetic acid, 5-35%) to give the title compound (25.5 mg, 0.047 mmol, 55%).
