Participants

Reaction Steps

To 2.51 g (~0.017 mole) of freshly distilled 4-chloro-N-methylaniline (b.p. 102-103° C.) is added 4.26 g (~0.017 mole) of 2-bromo-benzenesulfonyl chloride (98 w/w %). The mixture is stirred until hot. Ten percent sodium hydroxide is added dropwise with stirring until the solution is slightly alkaline. The 2-bromo-4'-chloro-N-methylbenzene-sulfonanilide is formed as viscous liquid. It is washed with water several times until the wash water is neutral. The compound is dried overnight at room temperature. The yield is 4.2 g (69% yield). 1H NMR (deuterioacetone): δ6.8-7.9 (m, 8 ArH), 3.2 (s, 3H, N--CH3).
