Reaction Steps

(R)-N2-(4-(2-Methyl-1H-imidazol-1-yl)phenyl)-N4-((tetrahydrofuran-2-yl)methyl)-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidine-2,4-diamine (56 mg, 0.14 mmol) was dissolved in methanol (3 mL). Acetic acid (7.91 μL, 0.14 mmol) was added followed by formaldehyde (10.28 μL, 0.14 mmol) and sodium cyanoborohydride (8.68 mg, 0.14 mmol). The reaction mixture was stirred at room temperature for 1 h and the solvent was evaporated under reduced pressure. The crude was purified by preparative HPLC yielding (R)-6-methyl-N2-(4-(2-methyl-1H-imidazol-1-yl)phenyl)-N4-((tetrahydrofuran-2-yl)methyl)-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidine-2,4-diamine (18.70 mg, 32.3%).
