Versuchsvorschrift

To a solution of 2-[5-(3-ethynyl-5-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl)-1,3-thiazol-2-yl]propan-2-ol (19 mg, 0.047 mmol) in ethyl acetate (1 mL) was added Pd/C (10 wt %, 10.0 mg, 9.4 μmol, and the reaction vessel was then purged with H2 and stirred under an atmosphere of H2 (balloon) overnight. The catalyst was deactivated by addition of dichloromethane, then the mixture was filtered through Celite (ethyl acetate rinse) and concentrated in vacuo. The residue was then purified by preparative HPLC (50-90% CH3CN in 15 mM NH4HCO3(aq)) which provided 12 mg (0.029 mmol, 63%) of 2-[5-(3-ethyl-5-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl)-1,3-thiazol-2-yl]propan-2-ol as a white solid. MS ESI: [M+H]+ m/z 409.1. 1H NMR (400 MHz, (CD3)2CO): δ 9.20 (s, 1H); 8.82 (d, J=4.9 Hz, 1H); 8.12 (s, 1H); 7.94 (s, 1H); 7.67 (s, 1H); 7.25-7.20 (m, 2H); 5.02 (s, 1H); 2.70 (q, J=7.6 Hz, 2H); 1.63 (s, 6H); 1.28 (t, J=7.6 Hz, 3H). rhSYK activity=+++
