Procedure
6-(4-Fluorophenyl)-1,2-dihydro-5-[4-(methylthio)phenyl]-2-oxo-pyridine-3-carbonitrile (Example 1, Step 5) (100 mg, 0.297 mMol), silver carbonate (82 mg, 0.297 mMol) and allyl chloride were stirred in a brown vessel in acetone (25 ml) for 48 hours. The reaction mixture was filtered. The filtrate was condensed to give the crude compound as a solid. 6-(4-Fluorophenyl)-5-[4-(methylthio)phenyl]-2-[(2-propenyl)oxy]-pyridine-3-carbonitrile was purified by silica gel chromatography and recrystallized from hexane. Anal. Calc'd. for C22H17N2OSF: C, 70.19; H, 4.55; N, 7.44. Found: C, 69.80; H, 4.60; N, 7.32.
