Participants

Reaction Steps

Alternatively, 2-[1-(4-(ethoxycarbonyl)piperazin-1-yl)carbonyl-3-(1,1-dimethylethoxycarbonyl)propyl]aminocarbonyl-4-[(1-(methoxycarbonyl)-3-(1,1-dimethylethoxycarbonyl)propyl)aminocarbonyl]quinoline (41 mg, 0.055 mmol) was treated with trifluoroacetic acid:methylene chloride (1:1, 0.6 mL) at ambient temperature for 2 hours. Evaporation of the reaction mixture, followed by dilution with methylene chloride, and repeated evaporation of the solvent gave 2-[1-(4-(ethoxycarbonyl)piperazin-1-yl)carbonyl-3-carboxypropyl]aminocarbonyl-4-[(1-(methoxycarbonyl)-3-carboxypropyl)aminocarbonyl]quinoline (40 mg) as a trifluoroacetic acid salt; NMR (CD3OD) 1.25 (t, 3), 1.95 (m, 1), 2.18 (m, 2), 2.40 (m, 1), 2.45-2.55 (m, 4), 3.45-3.92 (m, 11), 4.16 (q, 2), 4.80 (m, 1), 5.25 (m, 1), 7.72 (t, 1), 7.86 (t, 1), 8.21-8.26 (m, 3) ppm.
