Procedure

To a solution of 2-[1-(4-(ethoxycarbonyl)piperazin-1-yl)carbonyl-3-(((1,1-dimethylethoxy)carbonyl)methoxy)carbonylpropyl]aminocarbonyl-4-((1,1-dimethylethoxy)carbonyl)methoxyquinoline (38 mg, 0.05 mmol) in 1 mL CH2Cl2, was added 2 mL trifluoroacetic acid, then the reaction mixture was stirred at ambient temperature for 3 hours. The reaction mixture was evaporated in vacuo to afford an oil. The oil was diluted in water (5 mL), adjusted to pH 4.5 by saturated NaHCO3, then extracted by ethyl acetate (3×10 mL). The organic layer was evaporated in vacuo to afford 2-[1-(4-(ethoxycarbonyl)piperazin-1-yl)carbonyl-3-((carboxy)methoxycarbonyl)propyl]aminocarbonyl-4-(carboxy)methoxyquinoline as a white solid (30 mg); NMR (DMSO-d6), 1.16 (t, 3), 1.90 (m, 1), 2.10 (m, 1), 2.45 (m, 2), 3.3–3.9 (m, 8), 4.02 (q, 2), 4.52 (q, 2), 5.04 (m, 1), 5.13 (s, 2), 7.46 (s, 1), 7.68 (t, 1), 7.84 (t, 1), 8.08 (d, 1), 8.23 (d, 1), 9.95 (m, 1) ppm.
