2-(3,3,3-trifluoropropyl)benzenesulfonamide

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: A mixture of 50.2 g of 2-(3,3,3-trifluoro-1-propenyl)-phenylsulfonamide, 500 ml of ethyl acetate and 5 g of a 5% Pd/C catalyst is shaken for 1/2 hour at 20°-25° C. in a hydrogen atmosphere. The catalyst is then filtered off, the mixture is concentrated by evaporation, and the residue is crystallised from a mixture of methylene chloride and ether to thus yield 49.6 g of 2-(3,3,3-trifluoropropyl)phenylsulfonamide, m.p. 148°-149° C. The catalyst is then filtered off the mixture is concentrated by evaporation the residue is crystallised from a mixture of methylene chloride and ether to thus yield 49.6 g of 2-(3,3,3-trifluoropropyl)phenylsulfonamide, m.p. 148°-149° C.
