6-Carbamoyl-4-chloro-7-methoxyquinoline (41 mg, 0.1744 mmol) and N-(2-fluoro-4-hydroxyphenyl)-N′-(4-fluorophenyl)-N-methylurea (57 mg, 0.2048 mmol) were dissolved in dimethylsulfoxide (1.0 ml), and then sodium hydride (8.4 mg, 0.2093 mmol) was added and the mixture was heated and stirred at 85° C. for 30 minutes. After cooling the reaction solution to room temperature, water was added and the precipitated crystals were filtered out. The crystals were then suspended in acetone: diethyl ether=1:2 and refiltered out, washed with diethyl ether and dried by aspiration to obtain the title compound (46 mg, 0.0961 mmol, 55.13%) as yellow crystals.
