Reaction Steps

8-Hydroxy-2-morpholinyl-4H-pyrido[1,2-a]pyrimidin-4-one (59 mg, 0.24 mmol) was dissolved in acetonitrile (10 ml) and then treated with anhydrous potassium carbonate (197 mg, 1.4 mmol) followed by 2-chlorobenzylbromide (46 mg, 0.29 mmol) and the mixture was stirred at 80° C. overnight. Upon cooling the mixture was adsorbed directly onto silica, then eluted through a silica column using ethyl acetate. The purified product was obtained as a tan solid (34 mg).
