Versuchsvorschrift

To a solution of 4-{4-[6-amino-5-(8-methylisoquinolin-3-yl)-pyridin-3-yl]-pyrazol-1-yl}-piperidine-1-carboxylic acid tert-butyl ester (11.0 mg, 0.0227 mmol) in DCM (0.40 mL, 6.2 mmol) was added 1.0 M of HCl in Et2O (0.60 mL, 0.60 mmol), and the mixture was stirred at ambient temperature for 2 h. Almost immediately an off-white solid precipitated. The solvents were evaporated, and the residue was suspended in Et2O, filtered off, and dried in vacuo overnight, yielding the title compound as yellow solid. It appeared to be hygroscopic during the filtration; however, after the washing and initial drying it appeared to be non-hygroscopic. 1H NMR (400 MHz, DMSO-d6): δ=14.6 (very brs, 1H), 9.60 (s, 1H), 9.18-9.07 (brm, 1H), 9.05-8.92 (brm, 1H), 8.88 (d, J=2.0 Hz, 1H, 8.86 (brs, 1H), 8.73 (s, 1H), 8.51 (s, 1H), 8.45 (d, J=2.0 Hz, 1H), 8.16 (d, J=0.4 Hz, 1H), 7.95 (d, J=8.4 Hz, 1H), 7.81 (dd, J=8.4, 6.8 Hz, 1H), 7.61 (d, J=6.8 Hz, 1H), 4.58-4.49 (m, 1H), 3.40 (brd, J=12.4 Hz, 2H), 3.12 (brq, J=12.2 Hz, 2H), 2.83 (s, 3H), 2.30-2.12 (m, 4H). MS(ES+): m/z=385.21 (43) [MH+], 302.15 (100) [MH+-piperidine]. HPLC: tR=1.80 min (polar—5 min, ZQ2).
