Reaction Steps
To a mixture of 2-fluoro-4-(trifluoromethyl)pyridine-3-carboxylic acid (1.06 g) and K2CO3 (0.701 g) in DMF (dry) (10 mL) was added MeI (0.317 mL). The mixture was stirred at room temperature for 3 h. The mixture was directly purified by column chromatography (silica gel, EtOAc/hexane) to give the title compound (1.13 g, containing EtOAc and hexane, ca. 75% purity).
