Ethyl Acetate → 4-(2-Hydroxyethanesulfonyl)benzene-1-sulfonamide

Participants

Reaction Steps

4-(2-Hydroxyethylthio)benzenesulfonamide (94.3 g, 0.40 mol) was added portionwise to a stirred solution of Oxone® (368.9 g, 0.60 mols) in H2O (3600 mL). After 18 hours the white solid was collected, washed with H2O and dried to give 72.6 g, mp 156°-162° C. An additional 12.3 g was obtained from the aqueous filtrate by extraction with ethyl acetate (3×1000 mL). Recrystallization from acetonitrile gave material with mp 163°-165° C.
