実験手順
N-(3-Acetyl-5-pentafluorosulfanylphenyl)-2,2,2-trifluoroacetamide (O3.075; 9.4 g) was admixed with semiconcentrated sulfuric acid (200 ml), and DCM (15 ml) was added. After stirring at 100° C. for 7 h, the mixture was left to stand overnight. Then the mixture was added to ice-water and extracted with EA. The combined EA phases were washed with saturated sodium hydrogencarbonate solution, dried over magnesium sulfate, filtered and concentrated by rotary evaporation. 6.36 g of the title compound were obtained.
