実験手順

A solution of 5-(3,5-dimethylphenylthio)-4-isopropyl-1-(2-hydroxyethoxymethyl)-2-methyl-1H-imidazole (1) (301 mg, 0.9 mmol) prepared in accordance with the method as described in WO 96/10019 and p-toluenesulfonic acid hydrate (180 mg, 0.945 mmol) in a mixture of methylene chloride (5 mL) - toluene (1 mL) was concentrated under reduced pressure. The obtained residue was dissolved in methylene chloride (9 mL), to which was added 1,1-dimethoxycyclopentane (1.17 g, 9.00 mmol), and the mixture was stirred for 3 hours. Triethylamine (0.19 mL) was added to the reaction mixture, and the mixture was concentrated under reduced pressure. The residue was purified by chromatography on an alumina column (eluate: hexane - ethyl acetate (2:1)) to give the compound 2 (285 mg, 73 %) as oil. Rf 0.45 (Al2O3 60, Type E, 2:1 hexane -EtOAc).
