Yield: 80%

Reaction Conditions:

with N-chloro-succinimide;potassium acetate in dichloromethane

Steps:

a a)
a) 2,6-dichlorobenzenesulfonyl chloride Into a mixture of 200 milliliters (hereinafter "mL") of acetic acid, water and dichloromethane (3/1/4, v/v/v), 2,6 dichlorobenzenethiol (10.0 grams (hereinafter "g"), 55.8 millimoles (hereinafter "mmol"), N-chlorosuccinimide (37.28 g, 279 mmol) and potassium acetate (2.29 g, 27.9 mmol) were added. The resulting mixture was stirred at 0° C., then warmed to room temperature overnight. The mixture was then diluted with 200 mL of dichloromethane, and washed with water (100 mL*3). The organic layer was dried (Na2SO4) and concentrated to give the desired product (11 g, 80%). 1H NMR (CDCl3): δ7.57 (d, 2H), 7.47 (t, 1H).
