Procedure

6-chloro-3-[2-hydroxy-4-(3-piperidin-1-ylpropoxy)phenyl]-2-methylpyrido[3,4-d]-pyrimidin -4(3H)-one (10 mg), 2-fluoroethyl tosylate (7.6 mg) and potassium carbonate (16 mg) were mixed in dimethylformamide (2 mL) and stirred at 80° C. for 10 hours. Distilled water was added, the mixture extracted with ethyl acetate, and dried with anhydrous sodium sulfate. The product was purified by silica gel thin layer chromatography (chloroform/methanol=10/1), and the title compound (8.5 mg, 77%) was obtained as a colorless solid.
