The Production Process of 5-Chloro-N-tert-butyl-2-thiophenesulfonamide

The production process of 5-Chloro-N-tert-butyl-2-thiophenesulfonamide involves several steps, which are described in detail below.

Step 1: Preparation of N-tert-butyl-2-thiophenesulfonamide
To prepare N-tert-butyl-2-thiophenesulfonamide, a mixture of N-tert-butyl thiophosphoric triamide and sodium hydroxide is heated, and the resulting exothermic reaction is maintained for several hours.
The product is then dissolved in a solvent, such as acetone or ethyl acetate, and the solution is treated with a solution of hydrogen chloride in a suitable solvent, such as water or ethanol.
The resulting precipitate is filtered and dried to obtain the desired product.

Step 2: Chlorination of N-tert-butyl-2-thiophenesulfonamide
To chlorinate N-tert-butyl-2-thiophenesulfonamide, a solution of the compound in a solvent, such as chloroform or dichloromethane, is treated with a solution of chlorine in a suitable solvent, such as hydrogen chloride or methylene chloride.
The resulting reaction mixture is then stirred for several hours, after which the solvent is evaporated, and the resulting residue is purified by chromatography on a suitable column, such as silica gel.
The desired product is then eluted with a suitable solvent, such as ethyl acetate or methanol.

Step 3: Purification of 5-Chloro-N-tert-butyl-2-thiophenesulfonamide
The product obtained from the chlorination step is purified by recrystallization from a suitable solvent, such as ethanol or acetonitrile.
The resulting crystals are filtered and dried to obtain the desired product, 5-Chloro-N-tert-butyl-2-thiophenesulfonamide.

Overall, the production process of 5-Chloro-N-tert-butyl-2-thiophenesulfonamide involves several steps, including the preparation of N-tert-butyl-2-thiophenesulfonamide, its chlorination, and the subsequent purification of the resulting product.
