실험 절차

A solution of N-(7-bromoisoquinolin-3-yl)cyclopropanecarboxamide (200 mg, 0.68 mmol), 4-chloro-2-(5,5-dimethyl-1,3,2-dioxaborinan-2-yl)benzonitrile (205 mg, 0.816 mmol), cesium carbonate (0.22 g, 0.68 mmol) and bis(di-tert-butyl(4-dimethylaminophenyl)phosphine) palladium dichloride (24.0 mg, 0.05 eq) in a mixture of acetonitrile and water (10 mL, 10:1) was purged with nitrogen and stirred at 90° C. for 45 minutes under microwave irradiation. Ethyl acetate (20 mL) was added to the reaction mixture and it was filtered. The solid was extracted with ethyl acetate (20 mL×4). The combined organic layer was dried over sodium sulfate, filtered and concentrated in vacuo. The residue was purified by HPLC separation to give the product (13.7 mg, 5.8%). LCMS (ESI): RT (min)=1.099, M+H+=347.9, method=A. 1H NMR (400 MHz, DMSO-d6) δ 11.04 (s, 1H), 9.24 (s, 1H), 8.54 (s, 1H), 8.33 (t, J=0.8 Hz, 1H), 8.08-7.72 (m, 5H), 2.09-2.05 (m, 1H), 0.88-0.83 (m, 4H).
