Reaction Steps

A solution of 2-(p-chlorophenyl)-3-[(p-chlorophenyl)sulfonyl]-5-(trifluoromethyl)pyrrole (2.15 g, 5.12 mmol), bromine (0.29 mL, 5.63 mmol) and sodium acetate (0.46 g, 5.63 mmol) in acetic acid is stirred at room temperature for 4 hours, treated with additional bromine (3 drops), stirred overnight at room temperature and poured into water. The resultant aqueous mixture is filtered to obtain a solid. Flash column chromatography of the solid using silica gel and a 1:5 ethyl acetate/hexanes solution gives the title product as a white solid (1.88 g, mp >230° C.).
