실험 절차

2-(2-(2-(2-((2-Ethyl-4-(piperidin-4-yl)phenyl)amino)-5-(trifluoromethyl)pyrimidin-4-yl)ethyl)phenyl)acetamide (8) (84 mg, 0.16 mmol) was dissolved in methanol (8 mL), 37% formaldehyde solution (53 μL, 0.66 mmol) was added and the mixture stirred for ten minutes at room temperature. Sodium tris(acetoxy)borohydride (174 mg, 0.821 mmol) was added, and after two hours the mixture was concentrated. The residue was diluted with 10% sodium hydroxide (15 mL) and brine (15 mL), and the mixture extracted with ethyl acetate (4×25 mL). The combined ethyl acetate phases were washed with brine, dried over sodium sulfate, evaporated and the residue evaporated from DCM to give the title compound (9) (72 mg, 84% yield) as a white solid; 1H NMR (400 MHz, d6-DMSO) δ 9.46 (s, 1H), 8.49 (s, 1H), 7.36 (s, 1H), 7.21 (t, J=4.6 Hz, 2H), 7.18-7.10 (m, 4H), 7.06 (dd, J=8.2, 1.6 Hz, 1H), 6.88 (s, 1H), 3.44 (s, 2H), 3.07-2.90 (m, 4H), 2.86 (d, J=11.3 Hz, 2H), 2.57 (q, J=7.5 Hz, 2H), 2.48-2.37 (m, 1H), 2.19 (s, 3H), 2.02-1.89 (m, 2H), 1.79-1.59 (m, 4H), 1.09 (t, J=7.5 Hz, 3H). LCMS Method C: rt 5.04 min; m/z 526.2 [M+H]+; m/z 524.2 [M−H]−.
