Procedure

After adding 200 mg of potassium carbonate and 0.1 ml of 2-(2-bromoethoxy)tetrahydro-2H-pyran to a solution of 80 mg of [2-(2-fluoro-3-hydroxy-5-methoxyphenyl)-2-[4-(5-methyl-[1,2,4]oxadiazol-3-yl)phenylimino]-1-methylsulfanylethylidene]carbamic acid methyl ester (Example 3d) in 1 ml of DMF, the mixture was stirred at room temperature for 14 hours. Water was added to the reaction mixture and extraction was performed with ethyl acetate. The organic layer was washed with water and dried through PRESEP™. The filtrate was concentrated, and the residue was purified by silica gel column chromatography (ethyl acetate-heptane) to give the title compound (69 mg) as a yellow oil.
