Yield:82113-65-3 82%
Reaction Conditions:
with sulfuric acid in toluene at 0 - 20; for 1 h;
Steps:
7.2
2) Weigh 29.44g benzyl bistrifluoromethylsulfonamide was dissolved in 80mL of toluene, after cooling to 0 ° C,Slowly add 98% concentrated sulfuric acid 6.5g, the reaction time at room temperature for 1h, until the reaction is completed,100 ml of ice water and 100 ml of dichloromethane were added and neutralized with 2 mol / L of sodium hydroxide solution,The organic layer was collected, magnesium sulfate was added to the organic layer and dried, filtered,After the filtrate was evaporated under reduced pressure to remove methylene chloride,Recrystallization from 50 mL of n-hexane afforded 13.38 g of bistrifluoromethanesulfonamide,The yield (based on benzyl bistrifluoromethanesulfonamide) was 82%.
