A solution of 9H-fluoren-9-ylmethyl({[(1S*,2R*,4R*)-1-(2-fluorophenyl)-2-(hydroxymethyl)-4-methoxycyclopentyl]amino}carbonothioyl)carbamate (340 mg) in methanol (20 mL)-concentrated hydrochloric acid (1 mL) was heated under reflux for three hours. The reaction solution was concentrated under reduced pressure. Acetonitrile (10 mL) and piperidine (2 mL) were added to the residue at room temperature, and the mixture was stirred at room temperature for one hour. The reaction solution was concentrated under reduced pressure. The crude product was purified by NH-silica gel column chromatography to obtain the title compound (130 mg).
