Benzenamine, 2-chloro-4-(methylsulfonyl)- → Acetanilide

Participants

Reaction Steps

2-Chloro-4-methylsulfonylaniline (2.06 g.) is diazotized and coupled with 3-(N-cyclohexyl-N-ethylamino)acetanilide (2.60 g.) in 40 ml. of 1:5 acid as described in Example 9, except that the coupling is buffered by the addition of ammonium acetate after the diazonium solution is added to the coupler. This azo compound, 2-(2-chloro-4-methylsulfonylphenylazo)-5-N-cyclohexyl-N-ethylamino)acetanilide, produces bright scarlet shades on polyester fibers.
