3.0 g of 4-chloro-5-formyl-2-phenylimidazole (Chem. Pharm. Bull. 1976, 24(5), 960), 7.0 g of 4-bromobenzyl bromide and 11.7 g of K2CO3 are stirred at RT for 20 h in 200 ml of DMF. The reaction mixture is then poured onto 500 ml of water, and the precipitate is filtered off with suction and chromatographed on silica gel using DIP. 3.9 g of an amorphous foam are obtained.
