Procedure

To a mixture of lithium chloride (0.295 g, 6.94 mmol) (flame-dried), 6-bromoisoquinoline (0.1805 g, 0.868 mmol), and Pd(PPh3)4 (0.0501 g, 0.0434 mmol) in a microwave reaction vessel, was added a solution of N-(5-(tributylstannyl)thiazol-2-yl)acetamide (0.561 g, 1.30 mmol) in DMF (2.00 mL, 0.868 mmol). The mixture was sealed and heated at 100° C. (oil bath) overnight. After cooling, the mixture (solidified) was diluted with EtOAc and water (2 mL each) and sonicated for 10 minutes. The resulting mixture was filtered, and the solid was washed with water and more EtOAc to provide N-(5-(isoquinolin-6-yl)thiazol-2-yl)acetamide (0.2177 g, 0.808 mmol) as a yellow solid. LCMS (M+H+) 270.3 calc. for C14H12N3OS 270.3; 1H NMR (400 MHz, DMSO-d6) δ ppm 12.32 (br s, 1H), 9.27 (s, 1H), 8.48 (d, J=5.67 Hz, 1H), 8.13-8.15 (m, 3H), 8.06 (d, J=7.20 Hz, 1H), 7.85 (d, J=5.67 Hz, 1H), 2.20 (s, 3H).
