실험 절차

7-[7-(tert-Butoxycarbonylamino)-7-methyl-5-azaspiro[2.4]heptan-5-yl]-6-fluoro-1-[(1R,2S)-2-fluorocyclopropyl]-8-methoxy-1,4-dihydro-4-oxoquinoline-3-carboxylic acid in which configuration of the tert-butoxycarbonylamino group in the substituent at position 7 is the same as the one produced in Example 9 (267.2 g) was suspended in isopropyl alcohol (1.6 L), and 6N hydrochloric acid (405 mL, 2.43 mol) was added to the suspension while the suspension was stirred in an oil bath at 55° C. The mixture was stirred at the same temperature for 3.5 hours, and after allowing to cool to room temperature, isopropyl alcohol (2.4 L) was added. The reaction vessel was cooled in a water bath at 5° C., and the mixture was stirred at the same temperature for 13 hours. The precipitated crystals were collected by filtration, and after air drying for several hours, the crystals were dried under reduced pressure at 40° C. to obtain 223.3 g (471 mmol, 92%) of the target compound as a yellow powder.
