Reaction Steps

To a stirred solution of 2-(1-azidopropyl)-6-methyl-3-phenyl-4H-pyrido[1,2-a]pyrimidin-4-one (0.030 g, 0.094 mmol) in tetrahydrofuran (0.24 mL) and water (0.06 mL) was added 1.0 M of trimethylphosphine in tetrahydrofuran (0.11 mL) at room temperature and the mixture was stirred at room temperature for 1 hour. To the mixture was added methylene chloride and the mixture was washed with brine, dried over magnesium sulfate, and evaporated to dryness under reduced pressure. The crude residue was used directly in next step. LCMS calculated for C18H20N3O (M+H)+: m/z=294.2. Found: 294.3.
