実験手順

Trifluoroacetic acid (1 mL) was added to a stirred 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) (185 mg, 0.301 mmol) in DCM (10 mL) and the resulting solution was stirred at room temperature for 2 hours. DCM (20 mL) and 10% NaHCO3 solution (10 mL) were added then the organic layer was dried (MgSO4) and evaporated to dryness under reduced pressure to give the title compound (2) (125 mg, 81%) as a colourless solid; 1H NMR (400 MHz, CD2Cl2) δ 8.49 (s, 1H), 8.31 (d, J=8.3 Hz, 1H), 7.91 (s, 1H), 7.28-7.12 (m, 3H), 6.94 (bs, 2H), 6.85 (d, J=8.2 Hz, 1H), 6.78 (dd, J=11.8, 3.1 Hz, 1H), 6.35 (s, 1H), 5.94 (s, 1H), 3.88 (s, 3H), 3.65 (s, 2H), 3.42 (d, J=12.3 Hz, 2H), 3.24-3.02 (m, 4H), 2.91 (t, J=11.3 Hz, 2H), 2.75-2.61 (m, 1H), 2.10-1.83 (m, 4H). LCMS Method C: rt 4.92 min; m/z 514.1 [M+1]+, 521.1 [M−1]+.
