Dimethylformamide → HCID 86617930, compound

Participants

Reaction Steps

To 2 ml of a DMF solution containing 75 mg of {2-(5-ethoxy-2-fluoro-3-hydroxyphenyl)-2-[4-(5-methyl-[1,2,4]oxadiazol-3-yl)phenylimino]-1-methylsulfanylethylidene}carbamic acid methyl ester, 100 mg of potassium carbonate and 0.1 ml of 2-(2-bromoethoxy)tetrahydro-2H-pyran were added. The resulting mixture was stirred at room temperature for 10 hours, and then water was added thereto. The mixture was extracted with ethyl acetate. The organic layer was washed with water and then dried through PRESEP™. The filtrate was concentrated, and the residue was purified by silica gel column chromatography (ethyl acetate-heptane) to give {2-{5-ethoxy-2-fluoro-3-[2-(tetrahydropyran-2-yloxy)ethoxy]phenyl}-2-[4-(5-methyl-[1,2,4]oxadiazol-3-yl)phenylimino]-1-methylsulfanylethylidene}carbamic acid methyl ester (51 mg) as a yellow oil.
