Reaction Steps

1.98 g of 80% strength sodium hydride is added in portions to a solution of 4.25 g of imidazole in 70 ml of dimethylformamide. Upon completion of hydrogen evolution the mixture is stirred for a further 3 hours at 60° C., after which a solution of 18.42 g of 3-[4-(phenoxy)-phenoxy]-1-bromopropane in 40 ml of dimethylformamide is added. The mixture is heated for 8 hours at 80° C. and then poured into 2.5 liters of ice water. The solid which separates out is filtered off in a desiccator, dried over calcium chloride and purified by filtration over silica gel. There is obtained 14.5 g (82%) of N-[(p-phenoxyphenoxy)-n-propyl]-imidazole; m.p.: 54.5°-55.5° C.
