Versuchsvorschrift

To a solution of tert-butyl({4-hydroxy-4-[5-(3-methyl-5-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl)-1,3-thiazol-2-yl]piperidin-1-yl}sulfonyl)carbamate (45 mg, 0.073 mmol) in DCM (0.7 mL) was added TFA (0.120 mL, 1.5 mmol) and the reaction was stirred at room temperature for 80 min, then more TFA (0.120 mL, 1.5 mmol) was added. After 90 min most volatiles were removed by N2 flow and vacuum. The residue was diluted with saturated aqueous NaHCO3 and ethyl acetate. The combined organic layers were dried and evaporated to give 4-hydroxy-4-[5-(3-methyl-5-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl)-1,3-thiazol-2-yl]piperidine-1-sulfonamide (31 mg, 0.06 mmol, 82% yield). MS ESI: [M+H]+ m/z 515.2. 1H NMR (600 MHz, CDCl3): δ 8.59 (d, J=4.8 Hz, 1H); 7.87 (s, 1H); 7.81 (s, 1H); 7.25 (s, 1H); 7.02 (s, 1H); 7.00 (d, J=4.8 Hz, 1H); 3.59 (d, J=12 Hz, 2H); 3.14 (m, 2H); 2.34 (s, 3H); 2.26 (m, 2H); 1.94 (d, J=12 Hz, 2H). rhSYK activity=+++
