Reaktionsschritte
To a solution of 2,6-dichloro-4-trifluoromethylpyridine (10 g, 46.3 mmol) in methanol (200 mL) was added 25% NaOH/MeOH (12.5 g, 13.2 mL, 231 mmol), which was then stirred at 50° C. for 2 h and then at room temperature overnight. The reaction mixture was extracted with pentane, and the extract was concentrated in vacuo to afford 2-methoxy-6-chloro-4-trifluoromethylpyridine (9.79 g), used without further purification.
