반응 단계
Hydrogen chloride is bubbled through a solution of 3,3′-difluorobenzil (20) (3.81 g, 15.7 mmol) and sulfamide (1.53 g, 15.9 mmol) in methanol (15 mL) for 0.5 min followed by heating at 66° C. for 2 h. The reaction mixture is cooled to RT, the solvent rotary evaporated, and the residue triturated from heptane to give 3.50 g of the product 21.
