Versuchsvorschrift

(±)-3-(1-Isopropyl-1H-pyrazol-3-yl)-3-[4-(7-methoxyquinolin-8-yl)-1,4-diazepan-1-yl]propanoic acid (220 mg, 0.50 mmol) and 2-(pyrrolidin-1-yl)ethanamine (114 mg, 1.0 mmol) were suspended in anhydrous DMF (6 mL). N,N-Diisopropylethylamine (0.2 mL, 1.2 mmol) was added and the mixture was stirred at ambient temperature for 5 min followed by addition of HATU (300 mg, 0.79 mmol). After 1 h at ambient temperature, LC-MS and TLC indicated completion of reaction (LC/MS [M+H]+ 534.6). Water (5 mL) was added and the mixture extracted with EtOAc (100 mL). The organic layer was washed with brine (3×30 mL) and concentrated. The residue was purified by silica gel chromatography using 2 to 5% MeOH in CH2Cl2 containing 0.5% aqueous NH4OH to afford the title compound (230 mg, 86%) as a light yellow solid. 1H NMR (400 MHz, CDCl3) δ 9.20 (br, 1H), 8.81 (d, 1H, J=2.8 Hz), 8.03 (d, 1H, J=8.4 Hz), 7.51 (d, 1H, J=8.4 Hz), 7.34 (d, 1H, J=2.8 Hz), 7.27 (d, 1H, J=8.8 Hz), 7.21 (dd, 1H, J=4.0 and 8.0 Hz), 6.16 (s, 1H), 4.52 (septet, 1H, J=6.8 Hz), 4.34 (br, 1H), 3.90 (s, 3H), 3.58 (m, 2H), 3.52-3.40 (m, 4H), 3.20-2.80 (m, 4H), 2.63 (t, 2H, J=6.8 Hz), 2.54 (br s, 4H), 2.20 (br s, 2H), 2.02 (m, 2H), 1.78 (br s, 4H), 1.47 (d, 6H, J=6.8 Hz).
