Versuchsvorschrift

To 15 mg (0.034 mmol) of 4-[5-(3-methyl-5-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}-phenyl)-1,3-thiazol-2-yl]piperidin-4-ol in THF/Water (3:1, 1 mL) was added 4.2 mg (0.052 mmol, 1.5 eq) of potassium cyanate and 2N hydrochloric acid (22 μL, 1.3 eq). The mixture was heated at 50° C. for 6 h and then another 1.5 eq of potassium cyanate and 1.5 eq HCl added and the mixture stirred at 50° C. overnight. The reaction was diluted with saturated aqueous NaHCO3 and was partitioned with ethyl acetate. The organic layer was washed with water and dried, filtered and solvent removed under reduced pressure. The residue was purified by column chromatography on silica gel (0-100% ethyl acetate in hexanes) to give 12 mg (0.025 mmol, 73%) of 4-hydroxy-4-[5-(3-methyl-5-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl)-1,3-thiazol-2-yl]piperidine-1-carboxamide as off-white solid. MS ESI: [M+H]+ m/z 479.2. 1H NMR (600 MHz, CD3OD): δ 8.68 (d, J=4.8 Hz, 1H); 7.99 (s, 1H); 7.87 (s, 1H); 7.40 (s, 1H); 7.10 (m, 2H); 3.91 (m, \2H); 3.28 (m, 2H); 2.34 (s, 3H); 2.16 (m, 2H); 1.83 (m, 2H). rhSYK activity=+++
