Procedure

Sodium hydride (60 wt %, 0.36 g) was added to dimethyl sulfoxide (10 ml), and the mixture was stirred at 50° C. for 30 min and was then cooled to room temperature. 4-Amino-2,5-dimethylphenol (1.23 g) was added to the cooled mixture, and the mixture was stirred at room temperature for 10 min. Next, 4-chloro-6,7-dimethoxyquinoline (1.00 g) was added thereto, and the mixture was stirred at 100° C. overnight. Water was added to the reaction solution, followed by extraction with chloroform. The chloroform layer was then washed with a saturated aqueous sodium hydrogencarbonate solution and was dried over anhydrous sodium sulfate. The solvent was removed by distillation under the reduced pressure, and the residue was purified by chromatography on silica gel by development with chloroform/acetone (1/1) to give the title compound.
