Procedure
To a mixture of acetic acid (9 μL, 0.15 mmol) and Si-carbonyl diimidazole (266 mg, 0.287 mmol) was added a solution of 4-[5-(3-methyl-5-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl)-1,3-thiazol-2-yl]piperidin-4-ol (Example 46, 50 mg, 0.115 mmol) and hydroxybenzotriazole (26 mg, 0.17 mmol) dissolved in N,N-dimethylformamide, and the resultant suspension was shaken in a Bohdan block overnight at room temperature. The reaction mixture was filtered and concentrated in vacuo, and the resultant residue was dissolved in DMSO and purified via HPLC (30-64% CH3CN:H2O) to provide 1-{4-hydroxy-4-[5-(3-methyl-5-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl)-1,3-thiazol-2-yl]piperidin-1-yl}ethanone.
