実験手順
A solution of the product from Example 82B (0.40 g, 2.6 mmol) in chloroform (50 mL) was treated with manganese dioxide (0.55 g, 7.8 mmol), stirred at room temperature overnight, filtered, solvent evaporated and the residue flash chromatographed over silica gel eluting with ethyl acetate:hexane (1:1) to provide 0.21 g 3-cyano-4-fluorobenzaldehyde.
