5-(Difluoromethoxy)-2-mercapto-1H-benzimidazole Chemical Properties,Usage,Production

Chemical Properties

Pale Yellow Solid

Uses

Pantoprazole EP Impurity C. Pantoprazole USP Related Compound C.

General Description

5-(Difluoromethoxy)-2-mercapto-1H-benzimidazole may be used in the synthesis of pantoprazole, a drug for treating gastroesophageal reflux disease and gastrointestinal disorders.

Synthesis

75-15-0

172282-50-7

97963-62-7

In a four-necked flask equipped with a mechanical stirrer, a reflux condenser and a thermometer, the alkaline solution was prepared: 6.6 g of sodium carbonate was dissolved in 20 g of tap water, stirred until completely dissolved, cooled slightly, and then 34.8 g of 4-(difluoromethoxy)benzene-1,2-diamine was added, stirring was continued for 20 minutes. The reaction mixture was heated to 30°C and 20 g of carbon disulfide was slowly added dropwise, controlling the dropwise temperature at 25-35°C. After the dropwise addition was completed, the temperature was raised to 30-40°C and the condensation reaction was maintained at this temperature for 6 hours. Subsequently, continue heating to 60-70°C and maintain this temperature for cyclization for 6 hours. After the reaction was completed, activated carbon was added for decolorization. The pH of the filtrate was adjusted to 5-6 with sulfuric acid, and after filtration, washing and drying, 33.2 g of 5-difluoromethoxy-2-mercapto-1H-benzimidazole was obtained in 95.4% yield (based on 4-(difluoromethoxy)benzene-1,2-diamine).
