Versuchsvorschrift

Example 95-1. 9-bromo-2-(4-cyclopropyl-1H-imidazol-1-yl)-7,8-dihydro-[1,4]diazepino[7,1-a]isoquinolin-5(4H)-one (1.48 g, 3.73 mmol), (6-fluoropyridin-3-yl)boronic acid (1.05 g, 7.45 mmol) and a solution of Na2CO3 (1.97 g, 18.63 mmol) in water (14.5 mL) was treated with DME (58 mL). The suspension was degassed, Pd(PPh3)4 (646 mg, 0.56 mmol) was added and the mixture was heated at 85° C. for 2 h. The mixture was allowed to warm to RT and the solvent was removed under reduced pressure. The residue was dissolved in DCM and extracted with water, saturated aqueous NaHCO3 solution and brine. The combined organic layers were dried with sodium sulfate, filtered and the solvent was removed under reduced pressure. The crude product was purified by flash-column chromatography over silicagel (Biotage Isolera Four, eluent: 1% MeOH in DCM for 3 min, then from 1% MeOH in DCM to 4% MeOH in DCM in 25 min, 4% MeOH in DCM for 5 min) to yield a beige foam (1.04 g). The residue was crystallized from AcOEt to afford the title compound as white crystals (720 mg). UPLC-MS: MS 414.2 (M+H+); UPLC rt 0.95 min. 1H NMR (600 MHz, DMSO-d6) δ ppm 0.66 (d, J=3.4 Hz, 2 H), 0.72-0.84 (m, 2 H), 1.70-1.88 (m, 1 H), 2.84 (br. s., 2 H), 3.72 (br. s., 2 H), 4.24 (br. s., 2 H), 7.18 (s, 1 H), 7.31 (d, J=8.5 Hz, 1 H), 7.43 (s, 1 H), 7.47-7.57 (m, 2 H), 7.97-8.14 (m, 3 H), 8.27 (s, 1 H).
