1-[2-[(6-Hydroxyhexyl)oxy]-3-[(4-methoxyphenyl)methoxy]propyl]-1H-imidazole (Example 23) (0.3 g, 0.00086 mol) was added to a suspension of sodium hydride (0.006 g of an 80% dispersion in oil, 0.002 mol) in dry tetrahydrofuran (5 ml) at 25° C. and the resulting slurry stirred for 1 hour at this temperature. Methyl iodide (0.284 g, 0.002 mol) was then added and the resulting suspension stirred at 25° C. overnight. The suspension was then evaporated under reduced pressure and the residue poured into dilute hydrochloric acid (6N, 20 ml) and washed with ethyl acetate (2×5 ml), the aqueous phase was then basified with solid potassium carbonate and the liberated oil extracted into ethyl acetate (10 ml), the organic phase was then dried and evaporated under reduced pressure to give the product which was purified by column chromatography (silica gel, 10% methanol in ethyl acetate) to give the title compound as a pale yellow oil.
