Reaction Steps
To a stirred solution of 2-[5-(3-methyl-5-{[4-(trifluoromethyl)pyrimidin-2-yl}amino]phenyl)-1,3-thiazol-2-yl]propan-2-ol (Example 4, 58 mg, 0.15 mmol) in DCM (1.5 mL) were added Et3SiH (0.18 mL, 1.1 mmol) and TFA (0.17 mL, 2.2 mmol). The reaction mixture was heated to 60° C. for 3 hr. Additional Et3SiH (0.18 mL) and TFA (0.11 mL) were added and the reaction was then heated to 80° C. for 1 d. The mixture was cooled to room temperature, diluted with ethyl acetate (75 mL) and washed with saturated aqueous NRHCO3 solution, water, and brine. The solution was dried over anhydrous sodium sulfate, concentrated, and purified by flash chromatography to give N-{3-methyl-5-[2-(1-methylethyl)-1,3-thiazol-5-yl]phenyl}-4-(trifluoromethyl)pyrimidin-2-amine (31.7 mg, 0.084 mmol, 57.3% yield) as a white solid. APCI: [M+H]+ m/z 379.1. 1H NMR (500 MHz, DMSO-d6) δ 10.25 (s, 1H), 8.83 (d, J=4.9, 1H), 7.98 (s, 1H), 7.93 (s, 1H), 7.44 (s, 1H), 7.28 (d, J=4.9, 1H), 7.14 (s, 1H), 3.27 (dt, J=6.9, 13.7, 1H), 2.31 (s, 3H), 1.34 (d, J=6.9, 6H). rhSYK activity=+++
