To a solution of 2-[1-(4-(ethoxycarbonyl)piperazin-1-yl)carbonyl-3-(methoxycarbonyl)propyl]aminocarbonyl-4-chloroquinoline (150 mg, 0.315 mmol) in DMSO (3.0 mL) was added (R)-3-hydroxypiperidine (68 mg, 0.5 mmol) and DIEA (65 mg, 0.5 mL). The mixture was heated at 110° C. for 18 hours. The crude reaction mixture was treated with lithium hydroxide (3.0 mL 0.25 M) for 4 hours. The reaction was purified by preparative HPLC to afford 2-[1-(4-(ethoxycarbonyl)piperazin-1-yl)carbonyl-3-carboxypropyl]aminocarbonyl-4-(3-hydroxypyrrolidin-1-yl)quinoline (41.0 mg); NMR (DMSO-d6) 1.2 (t, 3), 2.00–2.20 (m, 4), 2.45 (m, 2), 3.30–3.75 (m, 8), 4.05 (q, 2), 4.60 (s, 1), 5.11 (m, 1), 7.39 (s, 1), 7.65 (m, 1), 7.95 (m, 1), 8.28 (m, 1), 8.58 (br s, 1), 9.75 (m, 1) ppm.
