Versuchsvorschrift

DIPEA (0.111 mL, 0.64 mmol) was added to a stirred solution of [(1H-Indole-5-carbonyl)-amino]-acetic acid (40 mg, 0.18 mmol) in DMF (1.0 mL). HOBT (29 mg, 0.22 mmol) and EDCI.HCl (42 mg, 0.22 mmol) were added, followed by the addition of piperazine-1-yl-(2-trifluoromethyl-phenyl)-methanone hydrochloride (59 mg, 0.20 mmol) at room temperature. The resulting mixture was stirred at room temperature overnight. The mixture was then diluted with water and the resulting precipitate was filtered to afford 1H-Indole-5-carboxylic acid {2-oxo-2-[4-(2-trifluoromethyl-benzoyl)-piperazine-1-yl]-ethyl}-amide in 45% yield. LC-MS purity: 91%, 1H NMR (CDCl3): δ 8.48 (s, 1H), 8.18 (s, 1H), 7.78-7.54 (m, 4H), 7.42-7.30 (m, 2H), 7.28 (s, 1H), 6.62 (s, 1H), 4.40-4.20 (m, 2H), 4.18-3.82 (m, 2H), 3.78-3.52 (m, 4H), 3.24 (s, 2H).
