Versuchsvorschrift

N-[2-Chloro-4-(4-aminophenylsulphanyl)phenyl]-2-acetoxy-2-methylpropanamide (Method 22) (0.50 g) was dissolved in DCM (10 m) and cooled to 0-5° C. in an ice bath. Triethylamine (0.55 ml) was added followed by dropwise addition of methylsulphonyl chloride (0.11 ml) and the mixture was allowed to warm to ambient temperature over 2 hours. The solution was concentrated then the solid was dissolved in DCM (5 ml) and water (5 ml) was added. The solution was loaded onto a Varian Chem Elut column and after 3 minutes was washed through with DCM (20 ml). The DCM layer was then concentrated and the solid washed with ether and filtered to give the title compound (0.58 g) as a solid. NMR (CDCl3): 1.7 (s, 6H), 2.2 (s, 3H), 3.4 (s, 6H), 7.2 (s, 4H), 7.4 (d, 1H), 7.5 (d, 1H), 8.4 (d, 1H), 8.5 (d, 1H); MS (ESP−): 533; EA: found: C, 44.4; H, 4.5; N, 5.1%; C20H23ClN2O7S3 requires C, 44.9; H, 4.3; N, 5.2%.
