실험 절차

A solution of 0.92 g (2.62 mmol) of 1-(2,4-difluorophenyl)-6,7-difluoro-1,4-dihydro-5-methyl-4-oxo-3-quinolinecarboxylic acid, 0.90 g (3.9 mmol) of (3R)-(1,-methyl-1'-t-butoxycarbonylaminoethyl)pyrrolidine (9a), 0.80 g (7.9 mmol) of triethylamine, and 50 mL of acetonitrile was heated at reflux for 18 hours. The solution was cooled to room temperature and concentrated in vacuo to an orange solid. The residue was chromatographed on E. Merck silica gel (230-400 mesh), eluting with 90:10 CHCl3:MeOH to give 1.47 g of (R) 7-[3-(1-t-butoxycarbonylamino-1-methylethyl)-1-pyrrolidinyl]-1-(2,4-difluorophenyl)-6-fluoro-1,4-dihydro-5-methyl-4-oxo-3-quinolinecarboxylic acid; NMR (CDCl3) δ8.47 (s, 1 H), 7.44 (m, 1 H), 7.15 (m, 2 H), 5.64 (d, J=7 HZ, 1 H), 4.47 (bs, 1 H), 3.50- 3.20 (m, 4 H), 2.85 (d, J=3.5 HZ, 3 H), 1.91 (m, 1 H), 1.74 (m, 2 H), 1.42 (s, 9 H), 1.29 (d, J=11 HZ, 6 H).
