Versuchsvorschrift

5-(9-Bromo-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepin-2-yl)-1-(2-chlorophenyl)-1H-1,2,4-triazol-3-ylcarbamic acid (600 mg, 1.2 mmol), 4-chlorophenylboronic acid (374 mg, 2.4 mmol), Pd(dppf)Cl2(97.9 mg, 0.12 mmol) and Cs2CO3 (469 mg, 1.44 mmol) were dissolved in dioxane/H2O (3:1, 30 ml). The resulting mixture was bubbled with N2 for 10 min and then sealed to stir at 120° C. for 4 h under N2. The reaction mixture was filtered. The filtrate was concentrated and purified by HPLC to give 1-(2-chlorophenyl)-5-(9-(4-chlorophenyl)-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepin-2-yl)-1H-1,2,4-triazol-3-ylcarbamic acid (270 mg, 21%). 1H NMR (DMSO, 400 MHz) δ 10.65 (s, 1H), 7.74 (s, 1H), 7.70 (d, J=8.4 Hz, 3H), 7.67-7.61 (m, 3H), 7.54 (t, 1H), 7.47 (d, J=8.4 Hz, 2H), 7.27-7.22 (m, 2H), 7.45-7.43 (m, 4H)
