Reaction Steps

To a stirred solution of the product of Step 4 (18.2 mg, 0.033 mmol) in dichloromethane (1 mL) was added TFA (1.00 mL, 12.98 mmol) and the mixture was stirred at room temperature. The solvent was removed by evaporation and stripped with ethyl acetate. The residue was concentrated and dried under high-vacuum to afford 1-(piperidin-4-yl)-1-[5-(3-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl)-1,3-thiazol-2-yl]ethanol (Example 15(2), 12.5 mg, 0.018 mmol) as a TFA salt.
