実験手順

7-(3-t-Butoxycarbonylamino-4-methyl-1-pyrrolidinyl)-1-cyclopropyl-6,8-difluoro-1,4-dihydro-4-oxo-3-quinolinecarboxylic acid (0.27 g) was dissolved in a mixture of methanol (5 ml) and concentrated hydrochloric acid (5 ml) and stirred at room temperature for 30 minutes. After the reacting mixture was concentrated under reduced pressure, the resulting residue was dissolved in ethanol (10 ml) and crystallized with cooling. The resulting precipitate was recrystallized from methanol to give the title compound (0.14 g) as pale yellow powder, mp 272°-274° C.
