Procedure

In 218 g of dry dimethylformamide was dissolved 21.8 g (58.5 mmol)of 2-benzyloxymethyl-5-(3-chlorophenylthio)-4-isopropyl-iH-imidazole (16e), followed by addition of 12.2 g (88.3 mmol)of anhydrous potassium carbonate and 11.6 g (81.7 mmol)of methyl iodide, the mixture was stirred at room temperature for 7 hours. To the reaction mixture was added ice-water, and the mixture was extracted with diethyl ether. The extract was washed with water and dried over sodium sulfate. The solvent was concentrated under reduced pressure and the residue was purified by silica gel chromatography (ethyl acetate:methylene chloride=1:8). From the first eluted fraction, 620 mg (yield 3%)of 2-benzyloxymethyl-4-(3-chlorophenylthio)-5-isopropyl-1-methyl-1H-imidazole (17ab') was obtained as oil. From the latter eluted fraction, 17.6 g (yield 78%)of 2-benzyloxymethyl-5-(3-chlorophenylthio)-4-isopropyl-1-methyl-1H-imidazole (17ab)was obtained as oil.
