Versuchsvorschrift

Example 137. A suspension of 2-(4-cyclopropyl-1H-imidazol-1-yl)-9-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-7,8-dihydro-[1,4]diazepino[7,1-a]isoquinolin-5(4H)-one (100 mg, 0.225 mmol), 2-bromo-5-fluoropyrazine (90 mg, 0.51 mmol) and Pd(PPh3)4 (39 mg, 0.034 mmol) in DME (2.8 mL) was treated with a 2M aq. solution of Na2CO3 (0.6 mL, 1.12 mmol). The mixture was heated to 90° C. for 2 h, allowed to cool to RT and poured onto H2O. The mixture was extracted with DCM and the combined org. layers were washed with brine, dried over Na2SO4, filtered and concentrated in vacuo. The crude product was purified by flash-column chromatography over silicagel (Biotage Isolera Four, eluent: 25% EtOAc in heptane for 2 min, then from 25% EtOAc in heptane to 100% EtOAc in heptane in 10 min, 100% EtOAc in heptane for 5 min) to yield a solid which was crystallized from diethyl ether and afforded the title compound (57 mg).
