実験手順

To a solution of 6.95 g (21 mmol) of N3 -(1,1-dimethylethyl)-N2,N2,1-trimethyl-1H-pyrrole-2,3-disulfonamide in 75 mL of methylene chloride under a nitrogen atmosphere was added 75 mL of TFA. The reaction mixture was allowed to stir at room temperature overnight ca. 16 hours. The reaction mixture was concentrated in vacuo. Three portions of diethyl ether were added to the solid residue and removed by evaporation to remove residual TFA. The solids were suspended in diethyl ether and filtered to yield 4.52 g of the title compound as a solid, m.p. 146°-148° C.
