실험 절차

A mixture of 2-(2-(2-(2-((4-(piperidin-4-yl)phenyl)amino)-5-(trifluoromethyl)pyrimidin-4-yl)ethyl)pyridin-3-yl)acetamide (32) (74 mg, 0.15 mmol), bromoethane (12 μL, 0.16 mmol) and potassium carbonate (63 mg, 0.46 mmol) in DMF (5 mL) was stirred for 48 h at room temperature under an inert atmosphere. The volatiles were removed under reduced pressure and the residue partitioned between ethyl acetate (20 mL) and saturated sodium hydrogen carbonate solution (20 mL). The aqueous layer was extracted with ethyl acetate (2×30 mL) and the combined organics were washed with brine then dried (MgSO4). The solvent was removed under reduced pressure and the resulting solid was chromatographed (Biotage Isolera: C-18 reverse phase column, 0-100% MeCN in H2O) to give the title compound (38) (22 mg, 28%) as an off-white solid; 1H NMR (400 MHz, d6-DMSO) δ 10.07 (s, 1H), 8.65 (s, 1H), 8.37 (dd, J=4.8, 1.7 Hz, 1H), 7.65-7.57 (m, 3H), 7.55 (s, 1H), 7.26-7.13 (m, 3H), 7.02 (s, 1H), 3.54 (s, 2H), 3.25 (s, 4H), 2.98 (d, J=11.3 Hz, 2H), 2.48-2.30 (m, 3H), 1.95 (q, J=11.7, 11.3 Hz, 2H), 1.73 (d, J=10.5 Hz, 2H), 1.63 (qd, J=12.4, 3.6 Hz, 2H), 1.03 (t, J=7.2 Hz, 3H). LCMS Method C: rt 4.16 min; m/z 513 [M+H]+.
