실험 절차

2-((2-(4-(Oxazol-5-yl)phenylamino)-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidin-4-yl)(phenyl)amino)ethanol (25 mg, 0.06 mmol, Example 1) was dissolved in methanol (1 mL). Acetic acid (0.013 mL, 0.23 mmol) and propionaldehyde (4.25 μL, 0.06 mmol) was added and the reaction mixture was stirred at room temperature for 10 minutes. Sodium cyanoborohydride (3.67 mg, 0.06 mmol) was added and after 15 minutes the solvent was evaporated under reduced pressure. The crude was dissolved in few drops of dimethylformamide and acetonitrile, filtered and purified by preparative HPLC yielding 2-((2-(4-(oxazol-5-yl)phenylamino)-6-propyl-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidin-4-yl)(phenyl)amino)ethanol (6.3 mg, 22.95%).
