Procedure

2-[1-(4-(Ethoxycarbonyl)piperazin-1-yl)carbonyl-3-(1,1-dimethylethoxycarbonyl)propyl]aminocarbonyl-4-[(1-(methoxycarbonyl)-3-(1,1-dimethylethoxycarbonyl)propyl)aminocarbonyl]quinoline (170 mg, 0.229 mmol) was treated with LiOH (2.0 eq.) in a solution of THF:H2O (3:1, 12 mL). The reaction mixture was stirred at ambient temperature for 5 hours. The pH value of the reaction mixture was adjusted to between pH 3 and pH4 with 1N HCl solution. The reaction mixture was evaporated in vacuo to afford a crude product, which was dissolved in ethyl acetate, washed with H2O and brine. The solvent was evaporated to give 2-[l-(4-(ethoxycarbonyl)piperazin-1-yl)carbonyl-3-(1,1-dimethylethoxycarbonyl)propyl]aminocarbonyl-4-[(1-carboxy-3-(1,1-dimethylethoxycarbonyl)propyl)aminocarbonyl]quinoline (150 mg); NMR (CD3OD) 1.30 (t, 3), 1.40 (s, 9), 1.50 (s, 9), 1.90 (m, 1), 2.15 (m, 2), 2.30–2.50 (m, 5), 3.45–3.90 (m, 8), 4.18 (q, 2), 4.75 (m, 1), 5.25 (m, 1), 7.75 (m, 1), 7.90 (m, 1), 8.25 (m, 3) ppm.
