Procedure

A 1:1 mixture of 7.7 g (49 mmol) of 4-hydroxymethyl-2-methoxymethyl-1-methylimidazole and 5-hydroxymethyl-2-methoxymethyl-1-methylimidazole and 7.3 g (55 mmol) of N-chlorosuccinimide was heated to 50° C. in 48 ml of ethylene glycol monoethylether and 70 ml of dioxane for 10 hours. Then the solvent was distilled off in vacuo and the crude product purified by chromatography (silica gel; methylene chloride/ethanol=99:1 to 90:10) to obtain the isomerically pure title compound.
