Reaction Steps

To a solution of 4-(2-Ethyl-3-{[4-(4-fluoro-phenyl)-thiazol-2-yl]-methyl-amino}-imidazo[1,2-a]pyridin-6-yl)-3,6-dihydro-2H-pyridine-1-carboxylic acid tert-butyl ester (60.0 g, 97 mmol, 1 eq.) in a mixture of THF (750 mL) and MeOH (750 mL) with AcOH (0.279 mL, 4.83 mmol, 0.05 eq.) was added Pd/C (10.3 g, 9.67 mmol, 0.1 eq.). The flask was evacuated and backfilled with argon. Then the reaction was evacuated and backfilled with H2 and stirred at r.t. under atmospheric pressure overnight. The crude product was filtered through a pad of Clarcel and washed with MeOH. The filtrate was concentrated under reduced pressure. The residue was purified to chromatography on silica gel to afford the expected compound.
