Procedure

Bromine (0.71 g, 4.42 mmol) is added to a solution of 2-(2-furyl)-5-(trifluoromethyl)pyrrole-3-carbonitrile (1.00 g, 4.42 mmol) and sodium acetate (0.36 g, 4.42 mmol) in acetic acid. The reation mixture is stirred for 15 minutes and poured into a 1% sodium bisulfite solution. The solids are filtered from the aqueous mixture, dried overnight under high vacuum and recrystallized from ethyl acetate and hexane to obtain the title product as red crystals (1.21 g, 90%, mp 224°-226° C.
