YieldReaction ConditionsOperation in experiment
Following the procedure of N. Ikemoto et al. (Tetrahedron, 59:1317 (1998)), <strong>[445-13-6]3-chloro-4-trifluoromethylaniline</strong> (890 mg, 4.6 mmol, Ryan Scientific) in CH3CN (37 mL) was added to a 250 mL round-bottomed flask. The flask was cooled in an ice bath, and HOAc (3.7 mL) and HCl (12 M, 1.8 mL) were added. Sodium nitrite (380 mg, 5.5 mmol, Aldrich) in 0.77 mL of H2O was added in 0.15 mL portions every 2 min until all of the solution had been added (total time ca. 9 min). After 25 min, sulfur dioxide (Aldrich) was bubbled into the reaction mixture for 1.25 h. Copper(II)chloride (780 mg, 5.8 mmol, Aldrich) in 1.5 mL of water was then added to the reaction mixture. Gas evolution occurred, and the reaction was warmed to RT and stirred overnight. After the lower boiling solvents were removed in vacuo, water was added, and the mixture was extracted with CH2Cl2 (3×). The combined organic layers were washed with water, dried over MgSO4, filtered and concentrated in vacuo to give the crude material as a brownish oil with solid in it. The compound did not ionize well, but an aliquot, when treated with propylamine, provided the propylarylsulfonamide adduct with a ESI-MS, -ion, m/z=300.2 (M-1).

YieldReaction ConditionsOperation in experiment
Example 12 4-Chloro-3-trifluoromethyl-2--isopropylthiobenzensulfonanilide (Compound No. 66) The procedure of Example 10 was repeated using 16.7 g of <strong>[6397-33-7]2-isopropylthioaniline</strong> and 27.9 g of 4-chloro-3-trifluoromethylbenzenesulfonyl chloride to yield 37.7 g of the title compound as a brown oil. Purification by silicagel-colum chromatography gave a colorless oil, n [23/D ] =1.5518.
