Procedure

1-[2-Hydroxy-3-(pentoxy)propyl]-1H-imidazole (Example 29b; 2.12 g, 0.01 mol) was added to a stirred suspension of powdered potassium hydroxide (2.24 g, 0.040 mol) in dimethylsulphoxide (10 ml) at 18° C. and stirred for 0.5 hours. 4-Methoxybenzyl chloride was then added and stirring was continued for 2 hours. Ethyl acetate (350 ml) was added and the solution was washed with water and dried (MgSO4). Ths solvent was evaporated off under reduced pressure and the crude product was purified by column chromatography (silica gel, chloroform) to give 1-[2-[(4-methoxyphenyl)methoxy]-3-(pentoxy)propyl]-1H-imidazole as a pale-yellow oil.
