Procedure

To a solution of 4-{4-[6-amino-5-(5-chloro-8-fluoroisoquinolin-3-yl)-pyridin-3-yl]-pyrazol-1-yl}-piperidine-1-carbaldehyde (50.0 mg, 0.111 mmol) in THF (5 mL, 60 mmol), cooled to ≈0° C., LiAlH4 (1.0M solution in THF; 0.27 mL, 0.27 mmol) was added, and the reaction mixture was stirred at 0° C.→rt for 30 min. Sodium sulfate decahydrate (0.1 g, 0.4 mmol) and EtOAc were added and the reaction mixture was stirred for 10 min at rt. The solids were filtered off, and the filtrate was concentrated and purified on prep-TLC eluting with 5% 7M NH3 (MeOH)/DCM to give the title compound as pale yellow oil. MS (ES+): m/z=436.79/438.74 [MH+]. HPLC: tR=2.24 min (ZQ2, polar—5 min).
