Versuchsvorschrift

To a solution of 1H-Indole-2-carboxylic acid {1[isopropyl-(4-methoxy-phenyl)-carbamoylmethyl]-2,4-dioxo-2,3,4,5-tetrhydro-1H-benzo[b][1,4]diazepine-3-yl}amide (0.14 g, 0.26 mmol) and 3-bromopyridine (40 μL, 0.42 mmol)in DMF (1 mL) was added copper powder (46 mg, 0.73 mmol) and acetic acid potassium salt (38 mg, 0.73 mmol). The heterogenous solution was stirred at 100° C. for 15 h and subsequently hot filtered through celite and washed with methanol. The resulting precipitate was filtered and purified by RPHPLC (40-60% C. over 30 min) to yield the title compound (19 mg) as a white lyophile: Tr=8.7 min (40-60% C. over 30 min); 1HNMR (d6 -Acetone, 300 MHz) δ 10.98 (s, 1H), 9.02 (s, 1H), 8.76 (s, 1H), 7.85 (d, 1H, J=8.8), 7.5 (m, 15H), 5.68 (d, 1H, J=7.6), 5.02 (m, 1H), 4.65 (ABq, 2H, J=16.8, 135), 4.02 (s, 3H), 2.19 (d, 3H, J=2.0), 2.18 (d, 3H, J=2.0); low resolution MS(FAB) m/e 617 (MH+).
