Reaction Steps
By employing the procedures described in Example 1, p-fluorophenylacetonitrile is reacted with diethyl oxalate in alcoholic sodium ethoxide to give ethyl 3-cyano-3-(p-fluorophenyl)pyruvate. The latter is reacted with phenylacetonitrile and subsequent synthetic steps yield 4-fluoropulvinic acid lactone. The lactone ring is opened with 2-aminothiazole as described above to give 4-fluoro-N-(2-thiazolyl)pulvinic acid amide.
