Chloroform → HCID 13913573, compound

Participants

Reaction Steps

5 ml of dry methylene chloride containing 304 mg of 3-chloroperbenzoic acid were added to 368 mg of methyl 4-[1-(2-methoxyphenyl)-2-(imidazol-1-yl)ethylthio]benzoate (prepared as described in Example 9) in 7 ml of dry methylene chloride, and the resulting mixture was stirred at 0°-5° C. for 30 minutes. At the end of this time, chloroform was added to the reaction mixture, and the resulting mixture was washed with a saturated aqueous solution of sodium chloride and dried over anhydrous magnesium sulfate. The solvent was removed by distillation under reduced pressure, and the residue was purified by silica gel column chromatography eluted with a 10:1 volume mixture of ethyl acetate and methanol, to give 263 mg of the title compound as colorless crystals, melting at 113°-115° C.
