Versuchsvorschrift

DIPEA (85.5 mg, 0.114 mL, 0.66 mmol) was added to a stirred solution of N-(2-Oxo-2-piperazin-1-yl-ethyl)-4-phenoxy-benzamide (60 mg, 0.176 mmol) in DMF (2 mL). HOBT (21.89 mg, 0.16 mmol) and EDCI.HCl (70.5 mg, 0.36 mmol) were then added at room temperature. After 2 minutes, 2-Bromo-5-methoxy benzoic acid (33.9 mg, 0.15 mmol) was added and the resulting mixture was stirred at room temperature overnight. The reaction mixture was then diluted with cold water, and the resulting precipitate was filtered, washed with water then hexane and dried to afford 70 mg (86.5% yield) of N-{2-[4-(2-Bromo-5-methoxy-benzoyl)-piperazin-1-yl]-2-oxo-ethyl}-4-phenoxy-benzamide as a pale yellow solid. LCMS Purity: 95.76%, HPLC Purity: 96.07%. 1H NMR (CDCl3): δ 8.5 (bs, 1H), 7.9 (d, 2H), 7.5 (m, 1H), 7.4 (m, 2H), 7.2 (m, 1H), 6.9 (m, 5H), 4.2 (m, 2H), 3.8 (s, 3H), 3.5 (m, 6H), 3.2 (m, 2H), 2.1 (s, 1H), 2.0 (m, 1H), 1.3 (s, 3H), 0.8 (m, 1H).
