Reaction Steps

In a pressure vessel, 107 g of 2,2,2-trifluoroethyl 2-nitrobenzenesulfonate and 8 g of 5% palladium-on-carbon in 300 ml of ethyl acetate was heated to 110° and shaken under 500 psi hydrogen pressure until hydrogen was no longer absorbed. The reaction mixture was cooled and the catalyst filtered off. The filtrate was stripped in vacuo to give 87.5 g of 2,2,2-trifluoroethyl 2-aminobenzenesulfonate as a dark oil.
