What is a two step synthesis of acetamidobenzenesulfonyl chloride?

This is an example of a two step synthesis. In the first week of the synthesis, you will prepare para-acetamidobenzenesulfonyl chloride from acetanilide. During the second week, this product will be converted into the sulfa drug sulfanilamide: HCl, H2O NaHCO3

What is P-acetamidobenzene sulfonyl chloride?

... 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).

How is acetamidobenzenesulfonamide hydrolyzed?

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.

How do you make sulfanamide from p-acetamidobenzenesulfonyl chloride?

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.
