Versuchsvorschrift

A flask containing a mixture of 2-(4-bromophenyl)-1-methylpyrrolidine (58.8 mg, 0.245 mmol), palladium acetate (8.9 mg, 0.040 mmol), 1,3-bis(dicyclohexylphosphino)propane bis(tetrafluoroborate) (35.5 mg, 0.0582 mmol), potassium carbonate (79.0 mg, 0.572 mmol), and N-(7-(5-amino-2-methylphenyl)isoquinolin-3-yl)cyclopropanecarboxamide (89.0 mg, 0.280 mmol) in N,N-dimethylformamide (2.0 mL, 26 mmol) was evacuated purged with nitrogen five times, and then evacuated and purged three times with CO gas. The reaction was stirred under a CO gas balloon, at 100° C., for 15 hours. The reaction mixture was poured into ethyl acetate, washed with saturated aqueous sodium bicarbonate and brine, dried over MgSO4, filtered, and evaporated in vacuo. The crude product was purified via flash chromatography on silica gel (12 g silica, solvent gradient: 0-10% methanol in dichloromethane) followed by purification via reverse phase HPLC and lyophilized to yield 10.3 mg (8%) of N-(3-(3-(cyclopropanecarboxamido)isoquinolin-7-yl)-4-methylphenyl)-4-(1-methylpyrrolidin-2-yl)benzamide. LCMS (ESI): RT=4.125, M+H=505.3, method=E; 1H NMR (400 MHz, DMSO-d6) δ 10.90 (s, 1H), 10.20 (s, 1H), 9.20 (s, 1H), 8.50 (s, 1H), 8.02 (s, 1H), 7.92 (t, J=8.2 Hz, 3H), 7.79 (s, 1H), 7.77-7.67 (m, 2H), 7.46 (d, J=8.0 Hz, 2H), 7.32 (d, J=8.3 Hz, 1H), 2.26 (s, 3H), 2.21-2.13 (m, 1H), 2.10 (m, 4H), 1.79 (m, 4H), 1.71-1.50 (m, 2H), 0.85 (m, 4H).
