... p-Acetamidobenzene sulfonyl chloride (p-ASC), is a derivative of sulfonated aromatic amines as shown in Fig. 1. It has been applied as an intermediate in the synthesis of p-aminobenzene sulfonamide (sulfanilamide, SN), one of the most frequently used sulfonamide type antibacterial medicines (Tan et al., 2011).
The corresponding acetanilide undergoes chlorosulfonation. The resulting 4-acetamidobenzenesulfanyl chloride is treated with ammonia to replace the chlorine with an amino group and affords 4-acetamidobenzenesulfonamide. The subsequent hydrolysis of the sulfonamide produces the sulfanilamide.
Step 1. Formation of the sulfanamide: Place 2.5 g of p-acetamidobenzenesulfonyl chloride into a 100-mL Erlenmeyer flask and add (under your hood) 7.5 mL of concentrated ammonium hydroxide. Stir the mixture well with a stirring rod. A reaction usually begins immediately and the mixture becomes warm.
