Procedure

To a solution of the product of Step 5 (150 mg, 0.289 mmol) in methanol (4 mL) was added HCl (4.0 M in dioxane) (0.072 mL, 0.289 mmol). After 30 minutes, the reaction mixture was concentrated. The residue was purified by preparative HPLC Reverse phase (C-18), eluting with acetonitrile/water 0.05% TFA to give 2-(5-{3-[(4-cyclopropyl-5-fluoropyrimidin-2-yl)-amino]-5-fluorophenyl}-1,3-thiazol-2-yl)propane-1,2-diol (95 mg, 0.24 mmol, 81%). MS ESI: [M+H]+ m/z 405.1. 1H NMR (600 MHz, DMSO-d6) 0.83 (s, 1H); 8.41 (s, 1H); 8.01 (s, 1H); 7.75 (s, 1H); 7.53 (d, J=11.4 Hz, 1H); 7.06 (d, J=9.6 Hz, 1H); 5.89 (s, 1H); 4.89 (s, 1H); 3.52 (s, 2H); 2.29-2.22 (m, 1H); 1.43 (s, 3H); 1.20-1.12 (m, 4H). rhSYK activity=+++
