Reaction Steps
To a solution of 5-[5-(3-{[4-(2-{[tert-butyl(dimethyl)silyl]oxy}ethoxy)pyrimidin-2-yl]amino}-5-methylphenyl)-1,3-thiazol-2-yl]-2,2-dimethyl-1,3-dioxan-5-ol (185 mg, 0.32 mmol) in tetrahydrofuran (1.6 mL) was added hydrochloric acid (1.0 N, 970 μL, 0.97 mmol) at room temperature. The mixture was stirred at room temperature for 2.5 h, then diluted with methanol, filtered, and purified by reverse phase HPLC (10:90 to 90:10 acetonitrile:water with a 0.1% trifluoroacetic acid modifier). The combined fractions were dried on a lyophilizer, dissolved in methanol, and the TEA salt converted to the free base using StratoSpheres SPE PL-HCO3 MP-Resin (0.9 mmol) cartridges to give 2-[5-(3-{[4-(2-hydroxyethoxy)pyrimidin-2-yl]amino}-5-methylphenyl)-1,3-thiazol-2-yl]propane-1,2,3-triol (75 mg, 0.18 mmol, 56% yield) as a white foam. MS ESI: [M+H]+ m/z 419.1. 1H NMR (500 MHz, DMSO-d6) δ 9.65 (dd, J=4.3, 15.1, 1H), 8.21 (d, J=5.7, 1H), 7.96 (s, 1H), 7.90 (s, 1H), 7.47 (s, 1H), 7.09 (s, 1H), 6.31 (s, 1H), 4.39 (s, 2H), 3.79-3.72 (m, 2H), 3.72-3.63 (m, 4H), 2.30 (s, 3H). rhSYK activity=+++
