実験手順

tert-Butyl 4-(4-((4-(2-(2-amino-2-oxoethyl)phenethyl)-5-(trifluoromethyl)pyrimidin-2-yl)amino)-3-ethylphenyl)piperidine-1-carboxylate, (I44) (120 mg, 0.20 mmol) was dissolved in DCM (20 mL), TFA (2 mL) was added and the mixture stirred for 16 hours at room temperature. The mixture was concentrated and the residue suspended in 10% sodium hydroxide (10 mL) and brine (10 mL). The mixture was extracted with ethyl acetate (4×20 mL), the combined extracts washed with brine, dried (sodium sulphate) evaporated and the residue evaporated for ether to give the title compound (8) (93 mg, 93% yield) as a white solid; 1H NMR (400 MHz, d6-DMSO) δ 9.47 (s, 1H), 8.49 (s, 1H), 7.37 (s, 1H), 7.26-7.18 (m, 2H), 7.17-7.09 (m, 4H), 7.05 (dd, J=8.2, 1.9 Hz, 1H), 6.89 (s, 1H), 3.44 (s, 2H), 3.09-2.88 (m, 6H), 2.62-2.54 (m, overlaps with DMSO), 1.70 (d, J=11.4 Hz, 2H), 1.52 (qd, J=12.3, 3.7 Hz, 2H), 1.10 (t, J=7.5 Hz, 3H), LCMS Method C: 4.96 min; m/z 512.2 [M+H]+, 534.2 [M+Na]+; m/z 510.2 [M−H]−.
