실험 절차

1-[2-Hydroxy-3-[(4-methoxyphenyl)methoxy]propyl]-1H-imidazole (Example 1b; 10 g, 0.038 mol) was added to a stirred suspension of powdered potassium hydroxide (8 g, 0.14 mol) in dimethylsulphoxide (20 ml) at 18° C. and stirred for 0.5 hours. Isopropyl 6-bromohexanoate (10.5 g, 0.044 mol) was then added and the mixture was stirred for 0.5 hours at 18° C. The mixture was poured into saturated aqueous ammonium chloride (1500 ml) and extracted with dichloromethane. The combined extracts were dried (Na2SO4) and the solvent was evaporated off under reduced pressure to give the crude product which was purified by column chromatography (silica gel, 2% ethanol in chloroform) to give isopropyl 6-[2-(1H-imidazol-1-yl)-1-[[(4-methoxyphenyl)methoxy]methyl]ethoxy]hexanoate as a pale-yellow oil.
