Procedure

To text-butyl 4-hydroxy-4-[5-(3-methyl-5-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl)-1,3-thiazol-2-yl]piperidine-1-carboxylate (50 mg, 0.093 mmol) in DCM (1 mL) was added 144 uL TFA (20 eq) and the reaction stirred at rt for 4 h. To the mixture was added saturated aqueous NaHCO3 and extracted with ethyl acetate. The organic layer was washed with water and brine. The combined organic layer was dried, filtered. The solvent was reduced in vacuo to give 40 mg (0.092 mmol, 98%) of 4-[5-(3-methyl-5-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl)-1,3-thiazol-2-yl]piperidin-4-ol. MS ESI: [M+H]+ m/z 436.2. 1H NMR (600 MHz, DMSO-d6): δ 8.81 (d, J=4.7 Hz, 1H); 7.93 (m, 2H), 7.44 (s, 1H); 7.25 (d, J=4.9 Hz, 1H); 7.13 (s, 1H); 5.97 (br s, 1H), 2.78-2.98 (m, 4H); 2.29 (s, 3H); 1.93-1.98 (m, 2H), 1.63-1.65 (m, 2H). rhSYK activity=+++
