Reaction Steps

4-{4-[6-Amino-5-(5-chloro-3,4-dihydro-1H-isoquinolin-2-yl)-pyridin-3-yl]-pyrazol-1-yl}-piperidine-1-carboxylic acid tert-butyl ester (26 mg, 0.051 mmol) was dissolved in MeOH (20 mL), 1.0 M of HCl in Et2O (20 mL) was added, and the mixture was stirred at rt overnight. The solvent was removed in vacuo to give the title compound as a brown solid. 1H NMR (400 MHz, CD3OD): δ=2.32-2.39 (m, 4H), 3.11 (t, J=6.0 Hz, 2H), 3.22-3.32 (m, 2H), 3.42 (t, J=6.0 Hz, 2H), 3.59 (d, J=13.2 Hz, 2H), 4.27 (s, 2H), 4.58-4.68 (m, 1H), 7.16 (d, J=7.6 Hz, 1H), 7.22 (t, J=8.0 Hz, 1H), 7.32 (d, J=8.0 Hz, 1H), 7.97 (s, 1H), 7.98 (s, 1H), 8.33 (s, 1H). MS(ES+): m/z=409.10/411.08 (46/18) [MH+]. HPLC: tR=2.25 min (ZQ2, polar—5 min).
