Versuchsvorschrift

DIPEA (133 mg, 0.18 mL, 1.0 mmol) was added drop wise to 4-(-phenyl-amino)-benzoic acid (75 mg, 0.35 mmol) in DMF (5 mL). EDCI (167 mg, 0.87 mmol) and HOBT (56 mg, 0.42 mmol) were added consecutively and, after 10 minutes, 2-amino-1-[4-(2,5-dichloro-benzoyl)-piperazin-1-yl]-ethanone in its TFA salt form (148 mg, 0.42 mmol) was added. The resulting mixture was stirred at room temperature overnight. Cold water was then added and filtered the solid to afford 140 mg (78% yield) of N-{2-[4-(2,5-dichloro-benzoyl)-piperazin-1-yl]-2-oxo-ethyl}-4-phenylamino-benzamide. LC-MS purity: 95.65%. 1H-NMR (DMSO-d6): δ 8.6 (s, 1H), 8.3 (t, 1H), 7.8 (m, 5H), 7.3 (t, 2H), 7.2 (m, 4H), 6.9 (t, 1H), 4.1 (d, 2H), 3.6 (m, 6H), 3.2 (d, 2H).
