실험 절차

To a suspension of 2-(2-(2-(2-((4-(piperidin-3-yl)phenyl)amino)-5-(trifluoromethyl)pyrimidin-4-yl)ethyl)phenyl)acetamide (4) (0.021 g, 0.043 mmol) in anhydrous methanol (2 mL) were added a 37% aq. solution of formaldehyde (0.006 g, 0.195 mmol) followed by sodium triacetoxyborohydride (0.046 g, 0.217 mmol) under an atmosphere of nitrogen. The reaction was stirred at room temperature for 1 hour, the volatiles were removed in vacuo and the residue was diluted with EtOAc (15 mL) and sat. aq. NaHCO3 (10 mL). The layers were separated and the aqueous layer was extracted with EtOAc (15 mL), the combined organic layers were washed with water (10 mL), brine (10 mL), dried (MgSO4), filtered and concentrated in vacuo to give the title compound (5) (20 mg, 93% yield) as a an off-white solid; 1H NMR (400 MHz, d4-MeOD) δ 8.54 (s, 1H), 7.62 (d, J=8.5 Hz, 2H), 7.30-7.15 (m, 6H), 3.67 (s, 2H), 3.19-3.12 (m, 2H), 3.12-3.02 (m, 2H), 2.96 (d, J=11.1 Hz, 2H), 2.85-2.74 (m, 1H), 2.34 (s, 3H), 2.13-2.03 (m, 2H), 1.96-1.67 (m, 3H), 1.49 (ddd, J=24.8, 12.5, 3.9 Hz, 1H). LCMS Method C: rt 4.86 min; m/z 498.3 [M+H]+.
