Procedure

A solution of tert-butyl 4-(4-((4-(2-(2-amino-2-oxoethyl)phenethyl)-5-(trifluoromethyl)pyrimidin-2-yl)amino)-3-methoxyphenyl)piperidine-1-carboxylate (I23) (2.694 g, 4.39 mmol) was dissolved in dichloromethane (150 mL), and TFA (15 mL) was added. The resulting mixture was stirred for 16 hours then concentrated. The residue was suspended in 10% sodium hydroxide (200 mL) then extracted with ethyl acetate (5×200 mL). The combined organic phases were washed with brine (300 mL), dried over sodium sulfate and evaporated to give the title compound (2) (2.252 g, 100% yield) as a white solid; 1H NMR (400 MHz, CDCl3) δ 8.53 (s, 1H), 8.26 (d, J=8.3 Hz, 1H), 7.85 (s, 1H), 7.29-7.21 (m, overlaps with CHCl3), 6.87 (d, J=8.3 Hz, 1H), 6.80 (s, 1H), 5.43 (d, J=10.1 Hz, 2H), 3.92 (d, J=1.3 Hz, 3H), 3.70 (s, 2H), 3.20 (d, J=12.7 Hz, 2H), 3.15-3.05 (m, 4H), 2.75 (t, J=12.2 Hz, 2H), 2.61 (tt, J=12.0, 3.5 Hz, 1H), 1.89-1.76 (m, overlaps with water), 1.67 (qd, J=12.7, 3.9 Hz, 2H). LCMS Method C: rt 4.92 min; m/z 514.1 [M+H]+, 536.1 [M+Na]+; m/z 512.2 [M−H]−.
