Bromoacetic anhydride (280 mg) is added to ethyl 8-amino-4-hydroxy-6-(4-morpholinylmethyl)-3-quinolinecarboxylate (Preparation 2, 330 mg) in DMF (4.0 mL). Triethylamine (400 mg) is added and the reaction is heated for 10 min at 60° C. After 1 h, the DMF is removed and the product is chromatographed on silica gel with 10% methanol as the eluant to give 310 mg of the title compound as a mixture with triethylamine hydrobromide. Physical characteristics: 1H NMR (DMSO-d6) δ1.40, 2.45, 3.56, 3.69, 4.39, 4.88, 7.49, 7.97, 8.34.
