実験手順
EDC (650 mg, 3.39 mmol) and dimethylamine (2.0 M solution in THF, 2.30 mL, 4.60 mmol) were added at room temperature to a solution of 6-chloro-3-(trifluoromethyl)pyridine-2-carboxylic acid (516 mg, 2.29 mmol) in dichloromethane (20 mL), and the mixture was stirred at room temperature for 4 hours. A saturated ammonium chloride aqueous solution was added to the reaction solution, followed by extraction with dichloromethane. The obtained organic layer was washed with brine and dried over anhydrous magnesium sulfate, and the solvent was distilled off under reduced pressure. The obtained residue was purified by silica gel column chromatography [elute: hexane/ethyl acetate=100/0-70/30 (gradient)] to obtain the title compound (246 mg, yield: 43%).
