A slurry of 2-isopropylimidazole (4.00 g, 36.3 mmol) in toluene (40 mL) at −78° C. was treated with 17.4 mL of a 2.8 M n-BuLi (48.7 mmol) solution in hexanes. This solution mixture was then refluxed for one day during which time the slurry became orange. The slurry was then filtered over a medium glass frit and dried to give a white solid.
