| Product | 3,4-Diphenyl-1,2,5-thiadiazole-1,1-dioxide | HCID 11000109 | 84,416% |
Reaction Steps
Hydrogen chloride is bubbled through a solution of benzil (24 g, 0.11 mmol) and sulfamide (11 g, 0.11 mmol) in methanol (120 mL) for 2 h followed by heating to reflux for 2 h. The reaction mixture is cooled to RT, and the precipitate that formed is filtered to give 25.1 g of the product 14.
