実験手順

In tetrahydrofuran (10 ml) was dissolved 245 mg (2 mmol) of 2-benzyloxymethyl-5-(3,5-dichlorophenylthio)-4-isopropyl-1H-imidazole (101a). To this solution, a methylene chloride solution of quinolin-3-ylmethylbromide was added at room temperature with stirring, followed by addition of 200 mg (5 mmol) of sodium hydroxide and 39 mg (0.12 mmol) of n-tetrabutylammonium bromide. After stirring for 2 hours, the mixture was left overnight and worked up. The reaction mixture was distilled off under reduced pressure. The residue was extracted with methylene chloride, and the extract was washed with water and dried. The solvent was distilled off, and the residual oil was purified by silica gel column chromatography (methylene chloride-ethyl acetate). As the first eluate, 26 g (2.6%) of 2-benzyloxymethyl-4-(3,5-dichlorophenylthio)-5-isopropyl-1-(quinolin-3-ylmethyl)-1H-imidazole (100a) was obtained. From the subsequent eluate, 730 mg of 2-benzyloxymethyl-5-(3,5-dichlorophenylthio)-4-isopropyl-1-(quinolin-3-ylmethyl)-1H-imidazole (100b) suited to the next step of the reaction was obtained (yield 73%).
