Reaction Steps

2,1 g of magnesium turnings are covered with 60 ml of dry tetrahydrofuran. A solution of 4-phenylbutylbromide (18,8 g) in 20 ml of dry tetrahydrofuran is then added dropwise to the mixture at such a rate that a smooth reaction is maintained. After the addition is complete, the reaction mixture is refluxed for one additional hour and cooled to room temperature. The reaction mixture is then added dropwise to a solution of 1-benzyl-5-imidazolecarbaldehyde (6,5 g) in 80 ml of tetrahydrofuran at 60° C. After the addition is complete, the reaction mixture is refluxed for 2 hours, cooled and poured into cold water. Tetrahydrofuran is evaporated and conc. hydrochloric acid is added to the solution. The product which is separated as an oil, is extracted with methylene chloride and evaporated to dryness.
