Reaction Steps

To a solution of tert-butyl 4-(4-((4-(2-(2-amino-2-oxoethyl)phenethyl)-5-(trifluoromethyl)pyrimidin-2-yl)amino)-3-fluorophenyl)piperidine-1-carboxylate (I61) (0.049 g, 0.081 mmol) in THF (3 mL) was added TFA (0.20 mL, 2.6 mmol). The resulting mixture was then stirred at room temperature for 20 hours then 40° C. for 24 hours. The volatiles were removed by evaporation under reduced and DCM (2 mL) and TFA (1.00 mL, 13.1 mmol) were added. After stirring at 30° C. for 18 hours the mixture was concentrated under reduced pressure and the residue azeotroped twice with toluene (10 mL) to give the title compound (I62) (0.037 g, 91%). LCMS Method C: rt 4.84 min; m/z 502.1 [M+H]+.
