Procedure

6-(4-Fluorophenyl)-1,2-dihydro-5-[4-(methylsulfonyl)phenyl]-2-oxo-pyridine-3-carbonitrile (Example 1, Step 6) (200 mg, 0.54 mMol), silver carbonate (150 mg, 0.54 mMol) and benzyl chloride (1 ml) were stirred in acetone (100 ml) and dimethylformamide (25 ml) at room temperature for 48 hours. The mixture was filtered and the filtrate was concentrated to a white solid which was recrystallized from chloroform-methanol: m.p. (DSC): 204.81° C. Anal. Calc'd. for C26H19N2O3SF (458.52): C, 68.11; H, 4.18; N, 6.11. Found: C, 67.81; H, 4.16; N, 6.04.
