실험 절차

N2-(4-(2-Methyl-1H-imidazol-1-yl)phenyl)-N4-((tetrahydro-2H-pyran-4-yl)methyl)-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidine-2,4-diamine (49 mg, 0.12 mmol) was dissolved in methanol (3 mL). Acetic acid (6.69 μL, 0.12 mmol) was added followed by formaldehyde (8.70 μL, 0.12 mmol). The reaction mixture was stirred at room temperature for 15 minutes and sodium cyanoborohydride (7.34 mg, 0.12 mmol) was added. After 1 h the solvent was evaporated under reduced pressure, the crude purified twice by preparative HPLC (acidic system) yielding 6-methyl-N2-(4-(2-methyl-1H-imidazol-1-yl)phenyl)-N4-((tetrahydro-2H-pyran-4-yl)methyl)-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidine-2,4-diamine (16.40 mg, 32.4%).
