A solution of 2,6-lutidine N-oxide (24.0 g, 0.20 mol) in anhydrous dichloromethane (400 mL) was added to trimethyloxonium tetrafluoroborate (29.6 g, 0.20 mol) at room temperature under nitrogen atmosphere and the reaction mixture was stirred at room temperature for 3 hours. The mixture was concentrated in vacuo to give the crude product, 1-methoxy-2,6-dimethyl-pyridinium tetrafluoroborate.
