Versuchsvorschrift
DIPEA (0.091 mL, 0.53 mmol) was added drop wise to furan-2-carboxylic acid (23 mg, 0.21 mmol) in DMF (5 mL). EDCI (84 mg, 0.44 mmol) and HOBT (28 mg, 0.21 mmol) were added consecutively and, after 10 mins, N-(2-Oxo-2-piperazin-1-yl-ethyl)-4-phenoxy-benzamide (60 mg, 0.18 mmol) was added and the resulting mixture was stirred at room temperature overnight. Water was then added, and the resulting solid was filtered under reduced pressure to afford N-{2-[4-(furan-2-carbonyl)-piperazin-1-yl]-2-oxo-ethyl}-4-phenoxy-benzamide in 65% yield. LC-MS purity: 92%, 1H NMR (DMSO-D6): δ 8.5 (t, 1H), 8 (t, 3H), 7.4 (t, 2H), 7.2 (t, 1H), 7 (m, 4H), 6.6 (s, 1H), 4.2 (d, 2H), 3.6 (m, 8H).
