실험 절차

N4-Ethyl-N2-(4-(oxazol-5-yl)phenyl)-N4-((tetrahydrofuran-2-yl)methyl)-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidine-2,4-diamine (125 mg, 0.30 mmol) was dissolved in methanol (3 mL). Acetic acid (0.017 mL, 0.30 mmol) was added followed by glycoaldehyde (17.85 mg, 0.30 mmol). The reaction mixture was stirred for 15 minutes at room temperature and sodium cyanoborohydride (18.68 mg, 0.30 mmol) (MP—CNBH3) was added. The reaction was stirred overnight at room temperature, the MP—CNBH3 was filtered off, the solvent was evaporated under reduced pressure and the crude was purified by preparative HPLC yielding 2-(4-(ethyl((tetrahydrofuran-2-yl)methyl)amino)-2-(4-(oxazol-5-yl)phenylamino)-7,8-dihydropyrido[4,3-d]pyrimidin-6(5H)-yl)ethanol (54.0 mg, 34.6%) as acetate salt.
