実験手順
1.22 g of 1-(t-butoxycarbonylamino)-3-azabicyclo[3.2.0]heptane, 0.96 g of 8-chloro-1-cyclopropyl-6,7-difluoro-1,4-dihydro-4-oxoquinoline-3-carboxylic acid and 0.58 g of 1,8-diazabicyclo[5.4.0]-7-undecene were added to 20 ml of acetonitrile, followed by heating under reflux for 3.5 hours. After the solvent was distilled off under reduced pressure, the resulting residue was purified by silica gel column chromatography (using a 100:1 mixture of chloroform and methanol as the eluent) and recrystallization (from ethyl acetate-diisopropyl ether) to obtain 0.96 g of 7-[1-(t-butoxycarbonylamino)-3-azabicyclo[3.2.0]hept-3-yl]-8-chloro-1-cyclopropyl-6-fluoro-1,4-dihydro-4-oxoquinoline-3-carboxylic acid (m.p. 200-202° C.).
