Procedure

To a 3 ml DMF solution containing 700 mg of {2-(3-hydroxy-5-hydroxymethylphenyl)-2-[4-(5-methyl-[1,2,4]oxadiazol-3-yl)phenylimino]-1-methylsulfanylethylidene}carbamic acid methyl ester there was added 440 mg of potassium carbonate and 0.15 ml of methyl iodide, and the mixture was stirred at room temperature for 17 hours and 30 minutes. Water was added to the reaction mixture and extraction was performed with ethyl acetate. The organic layer was washed with water and saturated brine, and then dried over anhydrous sodium sulfate. The desiccating agent was filtered off and the filtrate was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate-heptane) to give the title compound (544 mg) as a yellow solid.
