실험 절차
A mixture of 2.32 g 2,2,2-trifluoroethanethiol, 1.12 prop-2-yne-1-ol, 300 mg potassium hydroxide and 40 ml dimethylformamide is stirred at ambient temperature for 20 hours. The mixture is poured into 150 ml of water and extracted with 100 ml ethyl acetate (3 times). The organic phase is washed with water, dried and concentrated. The crude product is purified by column chromatography to obtain 75 mg of pure 1-hydroxy-3-(2,2,2-trifluoroethylthio)-prop-2-ene.
