Procedure

To tert-butyl 2-{[2-({3-[2-(1-hydroxycyclobutyl)-1,3-thiazol-5-yl]-5-methylphenyl}amino)-pyrimidin-4-yl]oxy}-2-methylpropanoate (Example 94A-25, 140 mg, 0.28 mmol) in DCM (1 mL) was added of trifluoroacetic acid (220 μL, 2.8 mmol). The mixture was aged for 2 hours and additional trifluoroacetic acid (500 μL, 6.4 mmol) was added. The reaction was stirred overnight. The reaction was concentrated under reduced pressure. Water was added and the mixture was extracted with ethyl acetate. The organic layer was dried, filtered and solvent removed under reduced pressure to afford 2-{[2-({3-[2-(1-hydroxycyclobutyl)-1,3-thiazol-5-yl]-5-methylphenyl}amino)pyrimidin-4-yl]oxy}-2-methylpropanoic acid (110 mg, 0.25 mmol, 88%) as pale yellow oil. MS ESI: [M+H]+ m/z 441.2. 1H NMR (600 MHz. DMSO-d6): δ 9.50 (s, 1H); 8.18 (d, J=6 Hz, 1H); 7.96 (s, 1H); 7.66 (s, 1H); 7.44 (s, 1H); 7.05 (s, 1H); 6.27 (d, J=6 Hz, 1H); 2.52-2.27 (m, 4H); 2.46 (s, 3H); 1.86 (s, 2H); 1.66 (s, 6H). rhSYK activity=++
