Reaction Steps

2-Morpholinyl-6-(4-hydoxyphenyl)-4-pyrone, as prepared in Example 5, (273 mg, 1.0 mmole) was suspended in 8 ml acetonitrile in a 25 ml one neck round bottom flask under nitrogen. The suspension was treated successively with potassium carbonate (829 mg, 6.0 mmole) and 2-chloromethyl-quinoline (533 mg, 3.0 mmole). The reaction mixture was stirred at 70° C. overnight. The acetonitrile was removed in vacuo and the residue was washed with 1×25 ml dichloromethane. The insoluble material was removed by filtration and the filtrate was concentrated in vacuo to a yellow solid. The crude material was washed with diethyl ether and was recrystallized from ethyl acetate to give 377 mg (91%) of Compound 8 as an orange solid.
