반응 단계
A solution of N-(3-trifluoromethylphenyl)-N'-ethoxycarbonylthiourea (1.8 g), dibromoethane (1.29 g) and anhydrous potassium carbonate (2.6 g) in acetone (20 ml) was refluxed for 5 hours. The solvent was removed by distillation, and the residue was extracted with diethyl ether. The extract was washed with water, dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was recrystallized from a mixture of hexane and ethanol to give 1.63 g of 2-ethoxycarbonylimino-3-(3-trifluoromethylphenyl)thiazolidine. m.p., 75.8° C.
