Reaction Steps

A mixture of 2,4,5-triphenyl-1-(7-bromoheptyl)-imidazole (0.95 g) and triethyl phosphite (1.66 g) in xylene (5 ml) was heated at reflux temperature for 20 hours. The mixture was evaporated to an oil and chromatographed on silica gel (ethyl acetate/ethanol) to give diethyl 7-(2,4,5-triphenylimidazol-1-yl)heptane-phosphonate (0.37 g, 35%) as a light brown oil.
