Procedure

Potassium t-butoxide (0.75 g, 6.7 mmol) is added portionwise at room temperature to a solution of 2,4,5-tribromopyrrole-3-carbonitrile (2.0 g, 6.1 mmol) in anhydrous tetrafuran (20 mL). After 30 minutes allyl iodide (1.12 g, 6.7 mmol) is added dropwise and then refluxed for 2 hours. Work-up as described in Example 15 gives the product as a pale pink liquid (2.1 g).
