Reaction Steps

A solution of ethyl 5-(p-chlorophenyl)-4-[(1,1,2,2-tetrafluoroethyl)sulfonyl]pyrrole-2-carboxylate (0.54 g, 0.0012 mol) in ethanol is treated under nitrogen with a solution of sodium hydroxide (0.26 g, 0.0065 mol) in water. The reaction mixture is refluxed for three hours, poured into ice-water, treated with hydrochloric acid and extracted with ethyl acetate. The combined organic extracts are washed with water and brine, dried over anhydrous sodium sulfate and concentrated in vacuo to obtain the title product as a gum (0.6 g).
