Reaction Steps

3-[5-(4-Amidino-2-fluorophenoxycarbonyl)thiophen-2-yl]-2,2-diethylpropanoic acid benzyl ester trifluoroacetic acid salt (4.3 g, 7.21 mmol) was dissolved in 2-propanol (160 mL) and water (40 mL), palladium hydroxide (0.9 g) was added, and the mixture was stirred at room temperature overnight under a hydrogen atmosphere. The reaction mixture was filtered through celite, and the filtrate was concentrated under reduced pressure. Water and acetonitrile was added to the residue, the mixture was lyophilized to give the title compound (3.61 g, 7.12 mmol, 99%).
