Procedure

Morpholine (0.018 mL, 0.204 mmol) and a few drops of AcOH (3.88 μL, 0.068 mmol) were added to a stirred suspension of 6-(6-methoxypyridin-3-ylamino)-5-(4-methyl-6-(methylthio)-1,3,5-triazin-2-yl)nicotinaldehyde (25 mg, 0.068 mmol) in EtOH (3.00 mL, 51.4 mmol), the mixture was stirred at room temperature for 1 h, then treated with sodium cyanoborohydride (4.26 mg, 0.068 mmol) and stirred at room temperature overnight. The mixture was diluted with water and EtOAc (10 mL each). The separated aqueous layer was extracted with ethyl acetate (2×10 mL) and the combined organic layers were washed with brine, dried over Na2SO4, and concentrated to give crude product which was purified by flash column chromatography (ISCO CombiFlash®, Teledyne ISCO, Lincoln, Nebr., DCM to 10% DCM in MeOH) to give N-(6-methoxypyridin-3-yl)-3-(4-methyl-6-(methylthio)-1,3,5-triazin-2-yl)-5-(morpholinomethyl)pyridin-2-amine (19 mg, 0.043 mmol, 63.7% yield) as a yellow solid. LCMS (API-ES) m/z 440 (M+H)+.
