実験手順
5.00 g of 4-pentafluorosulfanylphenol were dissolved in 50.00 g of dimethyl carbonate and 3.46 g of DBU were added. The mixture was boiled under reflux for 10 hours, then allowed to cool and diluted with 200 ml of EA. Subsequently, the mixture was washed twice with 100 ml each time of a 5% aqueous HCl solution, then with 100 ml of a 5% aqueous NaOH solution. Drying was effected over MgSO4 and the solvent was removed under reduced pressure. Chromatography on silica gel using 1:1 DIP/HEP afforded 2.2 g of a colorless oil.
