1-Ethyl-3-(3'-dimethylaminopropyl)carbodiimide → HCID 178510407, compound

To a flask containing 3-morpholin-4-yl-propionic acid potassium salt (94 mg, 0.47 mmol, prepared from 3-morpholin-4-yl-propionic acid ethyl ester exactly as described in Example 7, 4-cyano-1H-imidazole-2-carboxylic acid (2-cyclohex-1-enyl-4-piperidin-4-yl-phenyl)-amide trifluoroacetic acid salt (179 mg, 0.36 mmol, as prepared in Example 14 (b)), EDCI (83 mg, 0.43 mmol), and HOBT (68 mg, 0.5 mmol) was added DMF (4 mL). To the stirred slurry was added DIEA (157 μL, 0.9 mmol) and the reaction was allowed to stir overnight. The reaction was diluted with H2O (10 mL) and extracted with EtOAc (2×25 mL). The combined organic extracts were dried (Na2SO4), concentrated in vacuo and the crude product was purified by silica gel preparative TLC to afford 10.4 mg (6%) of the title compound as a white solid. 1H-NMR (CDCl3; 400 MHz): δ 1.49-1.93 (m, 5H), 2.22-2.31 (m, 3H), 2.52 (br s, 4H), 2.58-2.63 (m, 3H), 2.74-2.76 (m, 4H), 3.10-3.17 (m, 2H), 3.72 (br s, 4H), 3.97-4.02 (m, 2H), 4.76-4.81 (m, 2H), 5.81-5.82 (m, 1H), 6.81-6.82 (m, 1H), 6.99-7.00 (m, 1H), 7.09-7.13 (m, 1H), 7.70 (s, 1H), 8.26 (d, 1H, J=8.2 Hz), 9.51 (s, 1H); Mass spectrum (ESI, m/z): Calcd. for C29H36N6O3, 517.28 M+H). found 517.3.
