Procedure

tert-Butyl 2-(4-((4-(2-(2-amino-2-oxoethyl)phenethyl)-5-(trifluoromethyl)pyrimidin-2-yl)amino)phenyl)morpholine-4-carboxylate (I91) (23 mg, 0.039 mmol) was stirred with DCM (3 mL) and TFA (0.3 mL). After 18 hours the mixture was concentrated and the residue suspended in 10% aqueous NaOH (1 mL) and brine (1 mL). The mixture was extracted with ethyl acetate (5×3 mL), and the combined ethyl acetate phases washed with brine (20 mL), dried over sodium sulfate and evaporated to give the title compound (22) (17 mg, 89%) as a white solid; 1H NMR (400 MHz, d6-DMSO) δ 10.19 (s, 1H), 8.67 (s, 1H), 7.74-7.67 (m, 2H), 7.42 (s, 1H), 7.27 (d, J=8.6 Hz, 2H), 7.25-7.21 (m, 1H), 7.19-7.14 (m, 3H), 6.91 (s, 1H), 4.32 (dd, J=10.1, 2.1 Hz, 1H), 3.86 (d, J=10.9 Hz, 1H), 3.58 (dt, J=11.2, 7.2 Hz, 1H), 3.50 (s, 2H), 3.15-2.98 (m, 4H), 2.89 (dd, J=12.3, 2.2 Hz, 1H), 2.72 (d, J=5.2 Hz, 2H). LCMS Method C: rt 4.75 min; m/z 486.1 [M+H]+, 508.0 [M+Na]+; m/z 484.1 [M−H]−.
