Participants

Reaction Steps

A solution of 1-(3-hydroxypropyl)-4,5-dihydroimidazole (1.0 g, 3.65 mmol) in tetrahydrofuran (15 ml) was reacted with carbon tetrabromide (1.43 g, 5.47 mmol) and triphenylphosphine (1.43 g, 5.47 mmol) at ambient temperature for 18 hours. Solvent evaporation in vacuo and purification by flash chromatography on silica gel, eluting with 10% methanol in dichloromethane, yielded 1-(3-bromopropyl)-4,5-dihydroimidazole (429 mg, 35% yield) as a white solid:
