Procedure
A mixture of (3,3,4,4,4-Pentafluoro-butane-1-sulfonyl)-acetonitrile (WO2007/060839) (0.50 g, 1.99 mmol), trifluoro-methanesulfonic acid 2-trifluoromethylsulfanyl-ethyl ester (WO 2007/147888) (0.55 g, 1.99 mmol), and K2CO3 (0.82 g, 5.97 mmol) in 1,2-dimethoxyethane (20 mL) was stirred under nitrogen at room temperature overnight. The reaction mixture was diluted with H2O (50 mL) and extracted with ethyl acetate (2×50 mL). The combined organic extracts were washed with brine (100 mL), dried over Na2SO4 and concentrated under reduced pressure. The residue was purified by column chromatography (SiO2, hexanes/EtOAc 19:1) to afford compound II-1 (0.28 g, 37%) as a white solid.
