실험 절차

To a suspension of 1-cyclopropyl-6,8-difluoro-7-[3-(4-Methyl-1,2,3-triazol-1-yl)pyrrolidine-1-yl]-1,4-dihydro-4-oxoquinoline-3-carboxylic acid (415.5 mg, 1 mmol) in 2.5 ml of methanol and 0.8 ml water at room temperature was added slowly 0.31 ml Of 45% N,N,N-trimethyl-2-hydroxyethyl-ammonium hydroxide in methanol (1 mmol). The solution was stirred at room temperature for an additional hour. This was filtered and the supernatant was evaporated under reduced pressure at 30° C. The residue was crystallized from acetone-methanol to yield after drying 420 mg of off-white solid, m.p. 188.7°-190.7° C. 1H NMR (D20) δ: 8.44 (s, 1H), 7.84 (bs, 1H), 7.62 (bd, 13.9Hz, 1H), 5.43-5.22 (m, 1H), 4.35-3.62 (m, 7H), 3.52 (t, 2H), 3.21 (s, 9H), 2.73-2.16 (m, 2H) 2.29 (s, 3H), 1.74-0.9 (m, 4H).
