HCID 6228Dimethylformamide溶媒

実験手順

To a suspension of lithium lactate (7.8 g, 81 mmol) in 100 mL of anhydrous dimethylformamide was added sodium hydride (60% dispersion in mineral oil, 3.2 g, 80 mmol). After stirring at room temperature for 30 min, 2-chloro-4-trifluromethylpyridine (10 g, 55 mmol) was added, and the mixture was heated at 100° C. overnight. The reaction was cooled to room temperature, poured into 500 mL of water, and was washed with hexane (200 mL). The aqueous solution was acidified with concentrated hydrochloric acid (pH>2), and was extracted with ether (2×500 mL). The combined extracts were washed with water and brine, dried over anhydrous sodium sulfate, filtered and concentrated to dryness to give the title compound.
