Reaction Steps

2-Chloro-6-(4-fluorophenyl-5-[4-(methylsulfonyl)phenyl]pyridine-3-carbonitrile (Example 7) (200 mg, 0.52 mMol) was added to freshly prepared sodium ethoxide (0.57 mMol) (from addition of sodium metal to ethyl alcohol) in ethyl alcohol (50 ml) and heated to 65° C. for 3.5 hours. The reaction mixture was cooled to room temperature. Water (3 ml) was added and the mixture was concentrated. The product was partitioned between water (50 ml) and ethyl acetate (50 ml). The ethyl acetate portion was dried over sodium sulfate, filtered and concentrated to a solid. The product was purified by a silica gel chromatography to give a white solid: m.p. (DSC): 207.22° C. Anal. Calc'd. for C21H17N2O3SF (396.44): C, 63.62; H, 4.32; N, 7.07. Found: C, 63.56; H, 4.32; N, 6.88.
