CAS：141776-47-8|2-Ethylsulfonylimidazo[1,2-a]pyridine-3-sulfonamide

Introduction and application of CAS：141776-47-8|2-Ethylsulfonylimidazo[1,2-a]pyridine-3-sulfonamide

Applications Sulfonylsulfonamide can be used as pharmaceutical synthesis intermediates and organic synthesis intermediates. It can be used in laboratory research and development processes and chemical and pharmaceutical synthesis processes, such as in the preparation of sulfonylsulfuron-methyl. Prepare 25.7g of the reactant 2-ethylthioimidazole [1,2-a]pyridine-3-sulfonamide (0.1mol), 0.1g of sodium tungstate as the catalyst and 250ml of acetic acid as the solvent and place them in the reaction bottle , the temperature was raised to 70°C, and 27.2g of hydrogen peroxide (0.24mol) with a concentration of 30wt% as an oxidizing agent was slowly added dropwise into the reaction bottle to perform the oxidation reaction. After the dropwise addition, the heat preservation reaction was continued for 5 hours. The reacted system was then cooled to 15°C. Suction filtration, the obtained filter cake was washed with 120 ml of water and dried at 80°C for 12 hours to obtain 26.0 g of the product 2-ethylsulfonylimidazole [1,2-a]pyridine-3-sulfonamide (sulfonyl sulfonamide ) is an off-white solid with a purity of 98%, a melting point of 198.5~201.6°C, and a yield of 88%.
