実験手順

After adding 1.8 g of potassium carbonate and 3 g of (2-bromoethoxy)-t-butyldimethylsilane to a solution of 3.45 g of [2-(4-cyanophenylimino)-2-(2-fluoro-3-hydroxy-5-methoxyphenyl)-1-methylsulfanylethylidene]carbamic acid methyl ester (Example (163b)) in 10 ml of DMF, the mixture was stirred at 50° C. for 5 hours. Water was added to the reaction mixture and extraction was performed with ethyl acetate. The organic layer was washed with water and dried over anhydrous magnesium sulfate. The desiccating agent was filtered off and the filtrate was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (heptane-ethyl acetate) to give the title compound (3.73 g, isomeric mixture) as a light yellow solid.
