Procedure: To a stirring suspension comprised of O-cyclopropylmethyl-hydroxylamine hydrochloride (5.40 g, 0.0437 mol) in dichloromethane (20 ml) at ambient temperature under a nitrogen atmosphere was added diisopropylethylamine (10.8 ml, 0.062 mol). A solution comprised of 2,3,4-trifluorobenzenesulfonyl chloride (Oakwood Products, Inc., 1.00 g, 4.34×10−3 mol) in dichloromethane (120 ml) was added dropwise to the reaction vessel containing the stirring suspension over a 12 minute period. The reaction mixture was stirred for another 12 minutes and was quenched with 10% aqueous hydrochloric acid (140 ml). The biphasic mixture was stirred vigorously for 16 hours. The layers were separated and the organic phase was dried (MgSO4) and concentrated to 6 ml volume. The concentrated solution was administered to a flash silica column (Biotage, 90 g of silica gel). Elution with dichloromethane afforded 0.8283 g of a white amorphous solid; 68% yield; 1H-NMR (400 MHz; CDCl3 signal offset to δ 7.03; values reported are uncorrected) δ 7.50 (m,1H), 7.10 (s,1H), 6.95 (m,1H), 3.59 (d, 2H, J═7.2 Hz), 0.80 (m, 1H), 0.31 (m, 2H), 0.02 (m, 2H); 19F-NMR (376 MHz; CDCl3) δ−122.65 (m, 1F), −129.37 (m, 1F), −156.20 (m, 1F); MS (APCl−) 280 (M−1, 100), 210 (55), 195 (45). was added dropwise to the reaction vessel containing the stirring suspension over a 12 minute period was quenched with 10% aqueous hydrochloric acid (140 ml) The biphasic mixture was stirred vigorously for 16 hours The layers were separated the organic phase was dried (MgSO4) concentrated to 6 ml volume Elution with dichloromethane

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%), The reaction mixture was then poured onto water extracted three times with ethyl acetate The combined organic phases were then washed twice with saturated aq. NaCl solution dried over Na2SO4 concentrated in vacuo The residue was chromatographed on silica gel (eluant: ethyl acetate/heptane 1:4)
