Procedure

To a solution of 3-(2-(2-((2-methoxy-4-(piperidin-4-yl)phenyl)amino)-5-(trifluoromethyl)pyrimidin-4-yl)ethyl)benzamide (5) (0.021 g, 0.04 mmol) in methanol (2.00 mL) was added acetaldehyde (0.010 mL, 0.18 mmol) followed by sodium triacetoxyborohydride (0.044 g, 0.21 mmol) under a N2 atmosphere. The mixture was then stirred at room temperature for 5 hours. The resulting mixture was concentrated under reduced pressure and purified using silica gel column chromatography (0-30% MeOH/EtOAc+1% 2 M ethanolic NH3). The product was further purified using mass directed auto-preparative HPLC to give the title compound (7) (3.5 mg, 16%); 1H NMR (400 MHz, d6-Acetone) δ 8.62 (s, 1H), 8.24 (m, 2H), 7.91 (s, 1H), 7.78 (ddd, J=7.5, 1.4, 1.4 Hz, 1H), 7.41 (m, 3H), 7.01 (d, J=1.7 Hz, 1H), 6.89 (dd, J=8.3, 1.7 Hz, 1H), 6.60 (m, 1H), 3.97 (s, 3H), 3.21 (m, 4H), 3.12 (m, 2H), 2.55 (m, 3H), 2.16 (m, 2H), 1.85 (m, 4H), 1.11 (t, J=7.2 Hz, 3H). LCMS Method C: rt 4.98 min; m/z 528.2 [M+H]+.
