Reaction Steps

5-(1-Chloroisoquinolin-7-yl)-N-phenyl-[1,2,4]triazolo[1,5-a]pyridine-2-amine. A degassed mixture of 1-chloroisoquinolin-7-ylboronic acid (288 mg, 1.38 mmol), 5-bromo-N-phenyl-[1,2,4]triazolo[1,5-a]pyridine-2-amine (400 mg, 1.38 mmol), potassium phosphate (296 mg, 2.76 mmol) and tetrakis (triphenylphosphine)palladium(0) (160 mg, 0.138 mmol) in dimethylsulfoxide (10 mL) was heated at 90° C. under nitrogen overnight. After being cooled down to room temperature, the reaction mixture was filtered, and the filtrate was concentrated in vacuo to give the crude product, which was washed with ethyl acetate to give 541-chloroisoquinolin-7-yl)-N-phenyl-[1,2,4]triazolo[1,5-a]pyridine-2-amine (200 mg, 38.7% yield) as a solid. 1H NMR (400 MHz, DMSO-d6) δ (ppm) 9.68 (br s, 1H), 9.23 (s, 1H), 8.45 (d, J=8.4 Hz, 1H), 8.41 (d, J=5.2 Hz, 1H), 8.27 (d, J=8.8 Hz, 1H), 8.01 (d, J=5.6 Hz, 1H), 7.69 (m, 4H), 7.44 (d, J=6.0 Hz, 1H), 7.23 (t, J=7.6 Hz, 2H), 6.85 (t, J=7.2 Hz, 1H); MS (ESI) m/z: 372.1 [M+1].+
