실험 절차

A mixture of 145.2 g of the triethylamine salt of 2-mercaptophenylsulfonamide obtained in accordance with Example P6 and 79.7 g of 2-bromo- 1,1 -difluoroethane in 600 ml of methanol is stirred for 16 hours at a temperature of from +55° C. to +60° C. The reaction mixture is then concentrated by evaporation. The residue is stirred with ice-water and the resulting suspension is filtered to yield 120 g (95% of the theoretical yield) of 2-(2,2-difluoroethylthio)-phenyl-sulfonamide having a melting point of from +111° C. to +112° C.
