Procedure

To 30.6 mmol 2,3,4-trifluoro-benzenesulfinic acid (acid (prepared in analogy to example 2.20(a) from 2,3,4-trifluoro-benzenesulfonyl chloride) and 91.8 mmol triethylamine in 20 ml DMF was added 61.2 mmol 1-chloro-3-iodopropane, and the mixture stirred at room temperature for 1 h. The reaction mixture was then poured onto water and extracted three times with ethyl acetate. The combined organic phases were then washed twice with saturated aq. NaCl solution, dried over Na2SO4, and concentrated in vacuo. The residue was chromatographed on silica gel (eluant: ethyl acetate/heptane 1:4) to afford the title compound. MS (m/e): 275.2 ({37Cl}M+H+, 33%), 273.1 ({35Cl}M+H+, 100%),
