Reaction Conditions

Reaction Steps

A suspension of 4-chloro-6,7-dimethoxyquinoline (1566 mg, 7.00 mmol), 4-aminophenol (917 mg, 8.40 mmol) and cesium carbonate (4561 mg, 14.0 mmol) in dimethyl sulfoxide (14 ml) was stirred at 100° C. for 18 hr. Water was added to the reaction mixture, and the mixture was extracted 3 times with ethyl acetate/tetrahydrofuran (=1/1). The solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography (ethyl acetate→ethyl acetate/methanol=60/40). Ethyl acetate was added to the obtained residue and the mixture was filtrated to give the title compound (1267 mg, 61%) as a white powder.
