Reaction Steps

TFA (0.1 mL 1.298 mmol) was added to the solution of racemic tert-butyl 4-hydroxy-4-((4-(3-methyl-5-((4-(trifluoromethyl) pyrimidin-2-yl)amino)phenyl)-1H-pyrazol-1-yl)methyl)piperidine-1-carboxylate (120 mg, 0.23 mmol) in dichloromethane (1 mL). The mixture was stirred at room temperature for 2 days. Additional TFA (0.2 mL) was added and the mixture was stirred for 16 hours. The mixture was purified on reverse phase HPLC (ACN/water with 0.1% TFA modifier) to afford 4-((4-(3-methyl-5-((4-(trifluoromethyl)pyrimidin-2-yl)amino)phenyl)-1H-pyrazol-1-yl)methyl)piperidin-4-ol. MS ESI calc'd for C21H24F3N6O [M+H]+433. found 433. 1H NMR (500 MHz, CD3OD) δ 8.65 (d, J=4.8, 1H), 7.96 (s, 1H), 7.86 (s, 1H), 7.83 (s, 1H), 7.31 (s, 1H), 7.06 (s, 1H), 7.05 (d, J=4.2, 1H), 4.20 (s, 2H), 3.31-3.17 (m, 4H), 2.33 (s, 3H), 1.94-1.78 (m, 2H), 1.73-1.65 (m, 2H).
