GENERAL METHODS: A mixture of 2-methoxypyridine (1c, 0.216 mg, 2 mmol) and acetyl chloride (2a, 0.157 mg, 2 mmol) was mixed with CTAB/CTAC (0.001 mol) in 1,2-dichloroethane. The resulting reaction mixture was heated in a controlled microwave synthesizer (Biotage Initiator+ SP Wave model, 0.200 W, 2.45 GHz, with an additional 60 W at steady state) for 5 min under reaction conditions of 100 °C and 2 bar pressure. Upon completion of the reaction, the target product 2-acetyl-6-methoxypyridine (3o) was isolated by column chromatography using ethyl acetate-petroleum ether as eluent for purification on silica gel.
