The procedure for the preparation of 3-(5,8-dichloroisoquinolin-3-yl)-5-(1-piperidin-4-yl-1H-pyrazol-4-yl)-pyridin-2-ylamine trihydrochloride was followed, except using trifluoromethanesulfonic acid 5,8-difluoroisoquinolin-3-yl ester in place of trifluoromethanesulfonic acid 5,8-dichloroisoquinolin-3-yl ester, affording the title compound as a yellow solid. 1H NMR (400 MHz, DMSO-d6): δ=2.09-2.30 (m, 4H), 3.04-3.17 (m, 2H), 3.41 (d, J=12.1 Hz, 2H), 4.48-4.59 (m, 1H), 7.57-7.68 (m, 1H), 7.79 (td, J=8.8, 3.6 Hz, 1H), 8.15 (s, 1H), 8.47 (s, 1H), 8.68 (s, 1H), 8.83 (br. s., 1H), 9.01 (br. s., 1H), 9.65 (s, 1H). MS (ES+): m/z=407.16 [MH+]. HPLC: tR=1.76 min (ZQ2, polar—5 min).
