4,4-二氟环己烷-1-碳硫酰胺

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 7.0 g 4,4-Difluoro-cyclohexanecarbothioic acid amide and 8.46 g 2-Chloro-4-methoxy-3-oxo-butyric acid methyl ester were dissolved in 70 ml ethanol and heated under reflux overnight. The cooled reaction mixture was evaporated under reduced pressure and the resulting residue was purified by silica chromatography with the eluent n-heptane:ethyl acetate=4:1=>2:1 to obtain 4.0 g 2-(4,4-Difluoro-cyclohexyl)-4-methoxymethyl-thiazole-5-carboxylic acid methyl ester as an oil. heated under reflux overnight The cooled reaction mixture was evaporated under reduced pressure the resulting residue was purified by silica chromatography with the eluent n-heptane
