A mixture of the 3-bromo-5-(4-(ethylsulfonyl)phenyl)pyridin-2-amine (100 mg, 0.29 mmol), 1-oxo-1,2,3,4-tetrahydroisoquinolin-6-ylboronic acid (75 mg, 0.29 mmol), PdCl2(PPh3)2 (7.0 mg, 0.01 mmol) and Na2CO3 in 3:1 MeCN:H2O was microwave heated at 150° C. for 3 min. At completion, the reaction mixture was filtered, then purified by preparatory HPLC to provide 6-(2-amino-5-(4-(ethylsulfonyl)phenyl)pyridin-3-yl)-3,4-dihydroisoquinolin-1(2H)-one as a pale yellow solid (48 mg, 41% yield) after reverse phase preparatory HPLC purification. 1H NMR (400 MHz, MeOD) δ ppm 8.37 (d, J=2.5 Hz, 1H), 8.06 (d, J=8.0 Hz, 1H), 7.94 (d, J=8.5 Hz, 2H), 7.89 (d, J=8.5 Hz, 2H), 7.81 (d, J=2.5 Hz, 1H), 7.53 (d, J=7.8 Hz, 1H), 7.49 (s, 1H), 3.56 (t, J=6.7 Hz, 2H), 3.19-3.27 (m, 2H), 3.07 (q, J=6.5 Hz, 2H), 1.25 (t, J=7.3 Hz, 3 H); MS (EI) m/z: 408 [M+H]+.
