실험 절차

2-Morpholinyl-6-(4-hydroxyphenyl)-4-pyrone, as prepared in Example 5, (273 mg, 1.0 mmole) was suspended in 6 ml dimethylformamide in a 25 ml one neck round bottom flask under nitrogen. The suspension was treated with sodium hydride suspension (192 mg, 4.0 mmole) and the reaction mixture was warmed to 55° C. for 40 minutes. The reaction was treated with 2-picolyl chloride hydrochloride (492 mg, 3.0 mmole) and the mixture was stirred 4 hours at 55° C. The reaction was poured into 50 ml 2N sodium hydroxide/ice and the precipitated solid was collected, washed with water and diethyl ether and was dried (188 mg). The crude material was recrystallized from ethyl acetate to give 123 mg (34%) of Compound 6 as an off-white solid.
