Participants

Reaction Steps

TFA (24 μL, 0.31 mmol) was added to a solution of N-{3-[1-(2-{[tert-butyl(dimethyl)silyl]-oxy}ethyl)-1H-pyrazol-4-yl]-5-methylphenyl}-4-(trifluoromethyl)pyrimidin-2-amine in dichloromethane (2 mL), and the reaction was allowed to stir for 30 minutes. The competed reaction was concentrated under reduced pressure. The residue was purified by reverse phase HPLC (ACN/water with 0.1% formic acid modifier to afford 2-[4-(3-methyl-5-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl)-1H-pyrazol-1-yl]ethanol.
