실험 절차
A solution of ethyl amino(thioxo)acetate (4 g) and 3-bromo-1,1,1-trifluoroacetone (3.1 ml) in ethanol (150 ml) was heated under reflux overnight. The reaction mixture was concentrated under reduced pressure, and the residue was diluted with water and extracted with ethyl acetate. The organic layer was washed with saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (NH, hexane/ethyl acetate) to give the title compound (3.56 g).
