Reaction Steps
To a solution of 1-[2-hydroxy-2-methyl-3-[(4-methoxyphenyl)methoxy]propyl]-1H-imidazole (3.2 g, 0.0116 mol) in dimethylsulphoxide (20 ml) at 10° C., potassium tert butoxide (2.1 g, 0.018 mol) was added in portions over 10 min. CAUTION (see, L. Bretherick, Royal Society of Chemistry, Hazards in the Chemical Laboratory, 3rd Ed. p. 307). After stirring for 5 mins. a solution of ethyl 6-bromohexanoate (2.58 g, 0.0116 mol) in dimethyl sulphoxide (5 ml) was added, the reaction mixture warmed to room temperature, and stirring continued for a further 45 min. The mixture was poured into water, neutralised with 1N hydrochloric acid and extracted with dichloromethane. The combined organic extracts were washed with water, dried (MgSO4) and solvent removed at reduced pressure. The title compound was isolated by column chromatography (silica gel, 3% ethanol in chloroform) as a yellow oil.
