Magnesium 2-(dioxidan-2-ide-1-carbonyl)benzoate--water (1/1/6) → N-{3-[2-(4-fluoro-1,1-dioxidotetrahydro-2H-thiopyran-4-yl)-1,3-thiazol-5-yl]-5-methylphenyl}-4-(trifluoromethyl)pyrimidin-2-amine

Reaction Steps

N-{3-[2-(4-fluorotetrahydro-2H-thiopyran-4-yl)-1,3-thiazol-5-yl]-5-methylphenyl}-4-(trifluoromethyl)pyrimidin-2-amine (Example 132, 140 mg, 0.308 mmol) was dissolved in a 2:1 v/v CH2Cl2/MeOH mixture (6 mL) and magnesium monoperoxyphthalate hexahydrate (286 mg, 0.462 mmol) was added. The reaction was stirred at room temperature for 2 hrs, diluted with aqueous 10% Na2S2O3 and water and extracted with CH2Cl2 (2×). The combined organic layers were washed with brine, dried (MgSO4), filtered and evaporated. Column chromatography on silica (gradient elution, 0 to 50% EtOAc in hexanes) afforded the title compound (0.118 g, 0.243 mmol, 79% yield) as a white solid. MS ESI: [M+H]+ m/z 487.0. 1H NMR (500 MHz, DMSO-d6) δ 10.30 (s, 1H), 8.84 (d, J=4.9, 1H), 8.14 (d, J=2.7, 1H), 8.04 (bs, 1H), 7.48 (bs, 1H), 7.29 (d, J=4.9, 1H), 7.22 (bs, 1H), 3.48-3.40 (m, 2H), 3.28-3.24 (m, 2H), 2.75-2.60 (m, 4H), 2.32 (s, 3H). rhSYK activity=+++.
