反応手順
A solution having 5.05 g (27.8 mmol) of 2-chloro-4-trifluoromethylpyridine and 3.59 g (66.5 mmol) of sodium methoxide dissolved in 40 ml of methanol was stirred under reflux with heating for 4 hours. Water was added to terminate the reaction, followed by extraction with diethyl ether. The organic layer was dried over anhydrous sodium sulfate and subjected to filtration on the pad of a silica gel cake. The solvent was distilled off under reduced pressure to obtain 4.19 g (yield: 85%) of 4-trifluoromethyl-2-methoxypyridine.
