Reaktionsschritte

3-Methoxypyridine (20.08g, 209 mmol) was dissolved in 100 mL of acetic acid. 30% H2O2 (28.3 mL, 275 mmol) was added and the reaction mixture was heated at 70° C. for six h. The cooled reaction mixture was concentrated and the residue dissolved in CH2Cl2 and stirred overnight with 20 g of solid potassium carbonate. The mixture was filtered and concentrated to give compound 762A (25.2g, 100%) as a light yellow solid which was characterized by 1H NMR and carried on to the next step.
