Reaction Steps

To a solution of 2-(2-(2-(2-((2-fluoro-4-(piperidin-4-yl)phenyl)amino)-5-(trifluoromethyl)pyrimidin-4-yl)ethyl)phenyl)acetamide (I62) (0.037 g, 0.074 mmol) in anhydrous methanol (3 mL) was added 37% aqueous formaldehyde (0.022 mL, 0.30 mmol) and sodium triacetoxyborohydride (0.081 g, 0.38 mmol) under a nitrogen atmosphere. The resulting mixture was stirred at room temperature for 1 hour. The volatiles were evaporated under reduced pressure and the residue taken up saturated aqueous NaHCO3 solution (25 mL). The resulting mixture was extracted with EtOAc (2×25 mL) then the combined organic layers were washed with brine (25 mL), dried (phase separation cartridge) and evaporated to dryness under reduced pressure. The residue was purified using silica gel column chromatography (0-50% MeOH/EtOAc with 1% 2 M ethanolic ammonia) to give the title compound (13) (0.020 g, 52%); 1H NMR (400 MHz, d6-Acetone+d4-MeOH) δ 8.54 (s, 1H), 7.88 (dd, J=8.5 Hz, 1H), 7.16 (m, 6H), 3.80 (s, 2H), 3.63 (s, 2H), 3.10 (m, 4H), 2.95 (m, 2H), 2.54 (m, 1H), 2.27 (s, 3H), 1.79 (m, 4H). LCMS Method C: rt 4.93 min; m/z 516.1 [M+H]+.
