Reaction Steps

N-(3-Methylphenyl)-N'-{4-[(6,7-dimethoxy-4-quinolyl)oxy]phenyl}thiourea (18 mg) obtained in Example 171, dicyclohexylcarbodiimide (35 mg) and a catalytic amount of diisopropylethyl amine were dissolved in methylene chloride (6 ml), to which a solution of cyanamide (23 mg) in THF (1 ml) was added, and the admixture was stirred at room temperature overnight. After removing the solvent by distillation, the resulting residue was purified by column chromatography on silica gel eluting with chloroform/methanol (100/1) to obtain 19 mg of the title compound (yield: 95%).
