Participants

Reaction Steps

Acetic acid (0.803 μL, 0.01 mmol) was added to a solution of N2-(3-methoxy-4-(4-methyl-1H-imidazol-1-yl)phenyl)-N4-phenyl-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidine-2,4-diamine (Example 7, 0.03 g, 0.07 mmol) and 2-hydroxyacetaldehyde (4.21 mg, 0.07 mmol) in MeOH (5 mL). The reaction mixture was stirred for 10 min and sodium cyanoborohydride (4.41 mg, 0.07 mmol) added. The reaction was stirred for an additional 15 min and solvent evaporated under reduced pressure. The crude product was dissolved in MeOH/DMSO and purified by preparative HPLC to give 2-(2-(3-methoxy-4-(4-methyl-1H-imidazol-1-yl)phenylamino)-4-(phenylamino)-7,8-dihydropyrido[4,3-d]pyrimidin-6(5H)-yl)ethanol (0.018 g, 53.5%). MS (ESI+)/(ESI−) m/z 472/470
