実験手順
To a solution of 2-chloro-6-methyl-4-(trifluoromethyl)nicotinonitrile (1 g, 4.5 mmol) in anhydrous methanol (20 mL) was added sodium methoxide (540 mg, 10 mmol). After stirring at room temperature for 2 hours, the resultant mixture was concentrated to give a residue. And the residue was purified by column chromatography (silica gel, petroleum ether/ethyl acetate=1:1) to give 2-methoxy-6-methyl-4-(trifluoromethyl)nicotinonitrile (0.9 g, 92%). LRMS (M+H) m/z: calcd 216.05. found 216.
