YieldReaction ConditionsOperation in experiment
38% With caesium carbonate; In N,N-dimethyl-formamide; at 80℃; To a solution of <strong>[4983-28-2]2-chloro-5-hydroxypyrimidine</strong> (4.13 g) in DMF (40 mL) were added ethyl 2-bromo-2,2-difluoroacetate (12.83 g) and cesium carbonate (20.59 g), and the mixture was reacted at 80°C overnight. The reaction solution was cooled to room temperature, and then poured into water. The mixture was extracted with ethyl acetate thrice. The organic layer was dried over magnesium sulfate, and then filtered. The filtrate was concentrated under reduced pressure. The resulting residue was purified by column chromatography on silica gel (hexane:ethyl acetate = 80:20 to 60:40) to give the titled compound (2.16 g) as a colorless liquid (yield 38percent).

YieldReaction ConditionsOperation in experiment
43% With caesium carbonate; In N,N-dimethyl-formamide; at 100℃; for 1h; To a solution of 93 mg (0.71 mmol) of 4-hydroxy-1-methyl piperidine in 1.0 ml of N,N-dimethylformamide, 0.28 g (0.86 mmol) of cesium carbonate and 0.32 mg (2.2 mmol) of methyl chlorodifluoroacetate were added, and the reaction solution was stirred at 100° C. for 1 hour. After completion of the reaction, the reaction solution was poured into water and extracted with ethyl acetate. The organic layer was washed with saturated sodium chloride aqueous solution and dried with anhydrous magnesium sulfate, and then the solvent was distilled off under reduced pressure. The obtained residue was purified by preparative thin layer chromatography [n-hexane/ethyl acetate=75/25 (V/V)] to provide 55 mg of the title compound as a colorless oil (yield: 43percent). 1H-NMR spectrum (500 MHz, CDCl3) delta ppm: 8.53 (2H, s), 6.62 (1H, t, J=71 Hz).
