Versuchsvorschrift

After adding 300 mg of potassium carbonate and 0.1 ml of 2-(2-bromoethoxy)tetrahydro-2H-pyran to a solution of 100 mg of {2-(3-hydroxy-4,5-dimethoxyphenyl)-2-[4-(5-methyl-[1,2,4]oxadiazol-3-yl)phenylimino]-1-methylsulfanylethylidene}carbamic acid methyl ester in 1 ml of DMF, the mixture was stirred at room temperature for 20 hours. Water was added to the reaction mixture and extraction was performed with ethyl acetate. The organic layer was washed with water and saturated brine in that order, and dried through PRESEP™. The filtrate was concentrated, and the residue was purified by silica gel column chromatography (ethyl acetate-heptane) to give (2-{3,4-dimethoxy-5-[2-(tetrahydropyran-2-yloxy)ethoxy]phenyl}-2-[4-(5-methyl-[1,2,4]oxadiazol-3-yl)phenylamino]-1-methylsulfanylethylidene)carbamic acid methyl ester (80 mg) as a yellow oil.
