実験手順

To a solution of 2.80 g (0.37 mole) of thiourea in 1200 mL of ethanol was added 11.40 g (0.37 mole) of 2-bromo-3-oxo-3-(2-trifluoromethyl-phenyl)-propionamide. After stirring at room temperature overnight, the mixture was concentrated under reduced pressure. Purification of the residue by silica gel chromatography, eluting with dichloromethane-methanol (gradient 100:0-80:20) gave 11.80 g of 2-carbamimidoylsulfanyl-3-oxo-3-(2-trifluoromethyl-phenyl)-propionamide as a yellow solid.
